D0C / 00 6 Description of the Invention (f) The present invention relates to a common-optical-path periscope, and in particular to a common-optical-path periscope A field of view switching and focusing driving mechanism for a common light path periscope. The periscopes on traditional tanks and armored vehicles are usually fixed on the turret and are moved by the turret at the same time as the gun barrel. Generally, periscopes need to have two wide-angle (wide field of view) and narrow-view (naiTOW field of view) output modes, and usually have to perform a focusing action after switching between the two perspectives to achieve the best output image. Into. The driving mechanisms for traditional perspective switching and focusing can usually be divided into two types. One is the design that integrates the driving mechanism for switching and focusing the perspective, and the other is the design that drives the perspective switching and focusing respectively. Among them, in order to integrate the driving mechanism for switching the viewing angle and focusing, the 90-degree swing arm method is used to replace another group of lenses, and the viewing angle is changed by changing the lens group. Although the above-mentioned lens group has a focusing function, there is no fine-tuning mechanism. The design that separately drives the switching of the viewing angle and the focus is to use a motor to rotate the guide rod, drive the ring gear by the guide rod, and then adjust the lens group to adjust the pitch by the displacement of the ring gear to achieve the purpose of focusing. However, new periscopes often have multiple output modes of optical machines, such as charge sensing devices (CCD), infrared thermal cameras (TTS), and laser measuring instruments (LRF) that can capture visible light. Device to obtain different modes of output, and the "common optical path periscope" is a new type of periscope, before each beam of beams enters the beam splitter, they all enjoy the same optical path, and there will not be beams of different wavelengths along different optical paths. The difference. This paper size is in accordance with Chinese National Standard (CNS) A4 (21 × X 297 mm). Please read it first *

The incident light 100 is reflected into the common periscope through the rotatable incident head mirror 102. After the incident light 100 is reflected by the incident head mirror 102, it is reflected downward by the parabolic mirror 104 and upward by the wide and narrow viewing angle aspheric mirror 106. The incident light 100 reflected by the wide-narrow viewing angle aspherical mirror 106 is projected onto the crosshair 108, and then the incident light 100 passes downward through the common light path derotator 110 to prevent the left and right caused by the rotation of the stage. The image rolls. Finally, the multiple beam splitters 112, 114, 116 and multiple lens groups 118, 120 are used to decompose the incident light 100 into multiple groups of light beams (image output). The above “common optical path periscope” refers to the fact that after passing through the stop mirror U0, the beams of different wavelengths are parallel to each other, and there is no difference in the progress of the beams of different wavelengths along different optical paths. Therefore, the common optical path periscope can effectively reduce the complexity of the configuration of the beam splitters 112, 114, 116 and the lens groups 118, 120.

The viewing angle driving system 20 can cause the aspherical mirror system 30 to rotate in the rotation direction 50, so that the aspheric mirrors with different curved surfaces can reflect the incident light 100, thereby achieving the purpose of switching the viewing angle. The focus driving system 40 can make the aspherical mirror system 30 move back and forth linearly in parallel with the incident light 100 by fine-tuning the direction 60, thereby achieving the purpose of fine-tuning the focus. Next, please refer to FIG. 3, which is a schematic diagram showing a detailed mechanism of a viewing angle switching and focusing system of a common light path periscope according to a preferred embodiment of the present invention. After briefly introducing the viewing angle switching and focusing system of the periscope of the common optical path in this embodiment in the second figure above, we will explain the detailed structures of the viewing angle driving system 20, aspherical mirror system 30, and focusing driving system 40. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs First, the aspherical mirror system 30 will be described. The aspherical mirror system 30 is composed of, for example, a base 300, a frame 302, a plurality of first elastic devices 304, and a plurality of aspherical mirrors 306. The lens frame 302 is arranged in the lens holder 300 by, for example, a plurality of elastic devices 304. The elastic device 304 is, for example, a spring. A plurality of aspherical mirrors 306 are arranged on the frame 302. The number of aspheric mirrors 306 is, for example, two, and they are arranged on the frame 304 in a back-to-back manner. In addition, the frame 302 has, for example, a notch 308 adjacent to the focus driving system 40. Since the frame 302 is arranged in the frame 300 by a plurality of elastic devices 304, if the frame 302 is actuated in an external force in the fine-tuning direction 60, the paper size is applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 meals) ) 514747 8483TWF.DOC / 006 A7 Printed by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs B7_ ^^ "-V. Description of the invention (stone), a straight line will be made along the direction of the inner axis 310 of the lens holder motion. The above-mentioned inner axis 310 of the lens holder is parallel to the light path of the incident light 100. Next, the viewing angle driving system 20 will be described. The viewing angle driving system 20 is disposed on one side of the aspherical mirror system 30. The viewing angle driving system 20 is composed of, for example, a viewing angle driving motor 200, a worm 202, a worm wheel 204, and a rotating shaft 206. Among them, 'the scourge 202 is rotated by the viewing angle drive motor 200, the worm gear 204 is rotated by the worm 202, and the rotation shaft 206 is rotated by the worm gear 204.' The rotation shaft 206 is in the aspherical mirror system 30. The lens mount 300 is connected and drives the lens mount 300 to rotate. In addition, the viewing angle driving system 20 further includes a first bearing 208 and a first limit switch 210. The first bearing 208 is, for example, mounted on the rotating shaft 206, and the first limit switch 210 is, for example, used to control the on / off of the viewing angle driving motor 200 to further accurately control the operation of the driving motor. The viewing angle driving system 20 is adapted to rotate the aspherical mirror system 30 such that one of the aspherical mirrors 306 in the aspherical mirror system 30 faces the incident light 100. As the viewing angle driving system 20 rotates the aspherical mirror system 30, different aspheric mirrors 306 face the incident light 100, thereby achieving the purpose of switching between different viewing angles. Generally, in the case of dual viewing angles, the rotation axis 206 is usually rotated by 0 degrees. Or two angles of 180 degrees. Among them, the rotation axis 206 is rotated by 0 degrees, for example, representing a mechanical position of a wide viewing angle (WVOF), and the rotation axis 206 is rotated by 180 degrees, for example, a mechanical position representing (NVOF). In addition, when the rotating shaft 206 is rotated from 0 degrees to close to 180 degrees or from 180 degrees to close to 0 degrees, the paper size of the first pole 10 applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) I. -------- ^ ---------.
