Display 110 is designed to project an image along light path 112. In the configuration of zone 1, the optical path Π 2 is along the display axis lu. Display lens 115 is along and perpendicular to optical path 112 and has a display lens focus 124. The display lens focus 124 is located on the optical path and the configuration area 1〇1 causes the display lens focus 124 to be located in the beam splitter 12A. The split volume of the sub-image imaging area 101 can be greatly reduced by focusing the display image before it is split. The small splitting volume allows the embodiment to use a small, lightweight splitter # and allows the HMD design to include advantageous configurations and additional optical components that improve image quality and increase the size of the image as viewed by the user. Configuration diagram! The embodiment produces an image by (approximate) collimated light diverging (or reflected from) by the display 11, thus placing the beam splitter 12 in proximity to the display lens focus 124. However, the embodiments are not limited to this configuration because the splitter 12〇 should be placed in the position that is best suited for the focused image. For example, if the display 11 emits, transmits, or reflects non-collimated light, the display image will be focused on a focus that is not the focus of the display lens 124 and the Beiga will configure the splitter 120 to be close to The position of the focus area. In the embodiment of the configuration of the use zone 101, the beam splitter 12 is an asymmetric V-mirror splitter consisting of a partial reflective surface 121 and a fully reflective surface 122. The proximity of the 5th surface 121, 122 will depend on the size of the beam splitter 12 and the amount by which the region 101 is configured to produce a reduced split volume. Further arranging the zone 1 0 1 ' such that the face 121 and the face 122 share a common edge and are arranged asymmetrically with respect to the display axis 111. The area 1 〇 1 can thus display the display sub-image of the display n \ O:\90\90318.DOC -10 - 1294528 mw. The _ _ sub-image is used to describe a plurality of images of the display of the wax formed by various embodiments of the present invention. Figure 1 shows all the information of the 匕δ display, but the embodiment can use multiple sub-images containing only one part of the image. When the partial reflection surface 121 is irradiated, a portion of the displayed image is reflected along the left-eye pupil 14G, and becomes a left-eye sub-image. A portion of the display image that is not reflected by the partial reflection surface 121 passes through and illuminates the complete reflection surface 122 to form a right-eye sub-image which is reflected along the right-eye sub-diameter 13G. As a result, the same left-eye sub-image and right-eye sub-image travel in opposite directions and contain the same image information. The left eye sub-image will travel along the sub-optical path i 4 , and be directed to the user's left eye 146. A left-eye reflector 142 is placed along the sub-optical path 140, which is a fully reflective surface&apos; configured to change the left-eye optical path 丨4〇 by 9〇. The direction is entered into the left eyepiece optics 145. The right eye sub-image will travel along the sub-light path 130 and be directed to the user's right eye 丨 36. A right-eye reflector 132, which is a fully reflective surface, is placed along the sub-optical path 130, and is arranged such that the right-eye optical path 130 changes by 90. The direction is entered into the right eyepiece optics 135. The right eyepiece optics 135 and the left eyepiece optics 145 can be a single lens or a combination of lenses. The lenses are designed to appropriately amplify the right eye image for viewing by the user's right eye 136 and for the user's left eye 146. Observed left eye image. Eyepiece optics 135 and 145 are adjustable single lenses, but other embodiments may use multiple lenses or may properly focus the right eye sub-image and the left eye sub-image for viewing by right eye 136 and left eye 146, respectively. Any configuration. The Ο \90\90318 DOC -11-1294528 k &amp; illuminator 100 reflectors 142, 132 are depicted as mirrors, but embodiments are limited to the use of mirrors to redirect a sub-path. Alternatively, the 稜鏡, 局 f5 reflecting surface, polarizing beam splitter, or any other suitable configuration can be used to redirect a sub-path. A shame can also be adjusted by the synchronous movement of the optical components to accommodate different IPDs for different users. When zone 101 is displaced by motion 155, right eyepiece optics 135 and left eyepiece optics 145 can be shifted by motion and 151, respectively, to form IPD 150a and IPD 1 50b. When the IPD distance l5〇a becomes 1?〇15, the zone 101 simultaneously moves 155 (observed downward from Fig. i) and moves to the face plane 17〇. When IPD15〇b becomes 1]?]〇15 (^, zone 1〇1 is removed from plane 170 (observed upward from Figure 1). These synchronous motions allow I to set 100 to adjust to IPD 15 (^ and 11&gt;]:) The entire range between 15〇b while maintaining a constant distance between the faces 122, 121 and the eyepiece lenses 135, 145, respectively, of the sub-paths 130 and 140. The device 1 can also be used by The diopter correction is performed with additional adjustment of the motion 153 of the left eyepiece optical dry device 145 and the motion 154 of the right eyepiece optical device 135. Figure 2 illustrates a perspective view of a head mounted device 200 configured in accordance with an embodiment of the present invention. The head mounted device 2 includes a zone 101 as described in relation to the pictorial operation, which operates to split the display image of the display 110 into a left eye image along the left eye pupil 140 and a right eye. The right eye sub-image of the light path 13〇 travels. With respect to the device 200, the left-eye transition optical element 243 is disposed along the left-eye optical path 14〇 to adjust the left-eye sub-image for the left-eye reflector 142 to reflect to the left eye.

The right eye transition optic 233 suitably adjusts the right eye display sub-image for reflection by the right eye reflector 132 onto the right eye diffuser 234. The right eye image strikes the right eye diffuser 234 and forms a real image. This snap image is suitably adjusted for the right eye 136 by the right eyepiece composite optics 235. Device 200 is capable of diopter correction by motion 253 of left-eye composite optics 245 and motion 254 of right-eye composite optics 235. &gt; The device 200 can also perform a 1-0 adjustment by a plurality of synchronized motions. The IPD 150 can be shortened by shifting the left-eye composite optics 245 to the right with motion 251 and shifting the right-eye composite optics 235 to the left with motion 252. With respect to the embodiment of Figure 2, the section 240 of the sub-optical path 140 is located between the transition optic 243 and the diffuser 244, and the section 23 0 of the sub-optical path π is located at the transition optics 233 and the diffuser 23 4 between.

Once a left eye display sub-image has been reflected by the first left-eye reflector 543, it will be reflected by the third left-eye reflector 544 and redirected to the left-eye diffuser 243. Similarly, a right eye display sub-image will illuminate a right eye reflector 丨3 2, causing the right eye sub-light path 130 to change by 90. direction. A right eye shows that the sub-image will be followed by a second right-eye reflector 5 3 3, which also causes the right-eye optical path 丨3 〇 to change by 90°. The right eye reflector 132 and the second right eye reflector 533 are disposed along a common right eye reflector axis 53 1 .

The right eyepiece 516 is composed of a second right eye reflector 533, a third right eye reflector 534, a right eye diffuser 233, and a right eyepiece optical device 135. Device 500 can be diopter corrected by motion 153 of left eyepiece optics ι45 and motion 154 of right eyepiece optics 135. As depicted in Figure 5B, device 5A can adjust IPD 150. In device 500, 'left eyepiece 560 can be rotated about axis 541 relative to left-eye reflector 142. When the left eyepiece 560 is rotated counterclockwise about the left eye reflector axis 541, the sub-optical path 14 is deflected by an angle φ from its original path. Similarly, the right eyepiece 561 is rotatable about the axis 531 relative to the right eye reflector 132 such that the sub-optical path 13 is deflected from its original path by an angle φ'. These deflections cause the left eyepiece 56A and the right eyepiece 561 to rotate into the adjusted IPr) 550 in the user's face plane.

The combined blue, green, and red light is collimated and illuminates the display 110 as it passes through the display optics 115. Figure 8 depicts illuminating the display 自 from a single direction, but embodiments are not limited to a single direction. In contrast, the illumination system of Figure 8 is not difficult to adjust to multi-directional illumination as shown in Figure 7. The embodiments of the present invention are not limited to configurations in which the image splitter is placed near the focus of the focusing optics. In contrast, embodiments of the present invention can reduce the splitting volume of various applications by locating the image splitter to split a display image that is focused in a small area. Figure 9 illustrates a reduced split volume formed by an embodiment of the present invention. In Fig. 9, the display 11 is illuminated, thereby forming a display image. . The black display shirt propagates along the optical path 11 2 disposed along the display axis 111. A display lens 115 having a non-lens focus 124a focuses the display image to provide a reduced split volume. The point at which the split volume is minimal will depend on the light that illuminates the display. When the display 11 is illuminated by the light source 908a located at the reflective display lens focus 92, the display lens 115 will collimate from the source reflector 707.
