Description of the invention (3) Body, extending the optical plane in a right angle relationship [The fine-to-vertical mirror of the module of the present invention is modified to be the first and other instruments along its learning plane. The embodiment of the present invention is to use a laser module to change and simplify the two levels of the above horizontal and vertical. For convenience of description, the hollow motor and the cone beam are referred to as beam expanders. Placing the two upper modules in a vertical relationship and splitting the symmetry axis into the beamlets produces two mutually perpendicular lights. Description The second beam The second beam produces two at least the director directions. Learn the deflector at right angles. Although the work of the simple vertical state is continued for two times of the face-to-face, at this time, the light reflects the following vertical first and will simultaneously hold the light in the extended beam or 90 〇 splitting.

Due to the mutually perpendicular optical plane determined by the present invention, the deflection of one optical deflector from the laser module provides that the other beam may be a plane at 45° to the incident light, and the reflected beam is used to make the projected beam and the input sheet. However, the two beams are difficult to be accurate and accurate. To overcome this problem, the two principles are usually based on the fact that when the light is reflected, the angle between the emitted light and the incident light is twice, and the incident light itself. The error of the incoming line deflection is only taken when the angle between them is 45 °, the two beams will

Description of invention (4) Effectively perpendicular to each other. Through a single piece of light guiding material, we make the two reflecting surfaces into one body, which forms a more stable pentagonal 稜鏡. The deflector has four optical surfaces: the two refractive surfaces are perpendicular to each other and the two reflecting surfaces are 45. The beam after two refractions and two reflections is effectively perpendicular to the original incident beam. In the application of the optical deflector of the present invention, the radiating end may simultaneously generate two mutually perpendicular spectroscopic optical elements, and the spectroscopic optical element may be a plane parallel transparent flat plate of a semi-reflective film which is at a temperature of 45° with incident light, such that A portion of the incident light, such as 50%, is reflected in a direction perpendicular to the incident, while the remaining portion, such as 50%, passes through the film in the incident direction to form a straight beam. The above-mentioned spectroscopic optical element may be a cubic crucible: it is formed by gluing two right-angle prisms along a slope thereof, at least one of which is plated with a semi-reflective film. Thus, a portion of the incident light, such as 50%, is reflected in a direction perpendicular to the incident, and the remaining 50% is coaxially penetrated in the incident direction. However, due to the effect of the parallel plate thickness of the coating, there will be a parallel translation between the two beams. In order to eliminate the positional deviation between the two lights, a compensation plane parallel transparent plate is introduced, and the displacement between the rays caused by the thickness thereof is offset to offset the displacement caused by the above-mentioned beam splitter. Similarly, in order to prevent the two beams from being accurately and accurately maintained in a vertical state, the spectroscopic optical element to which the present invention is applied may also use two plane-parallel transparent plates having an angle of 45°, in which a plane that faces light from the light source is faced. The parallel transparent plate is plated with a semi-reflective film while the other plane is plated with a reflective film. Incident

Description of invention (5) The light is first directed to a transparent plate coated with a semi-reflective film, a part of which is like 50% 'passing in the incident direction, which is not in the transparent plate, travels in the original direction, leaving the remaining 50%. Then, it is reflected on the parallel plate of the reflective film, and two consecutive reflections form a beam perpendicular to the incident light. In the pentagonal rib, in order to pass part of the light through the cymbal in the original direction, the light reflecting surface from the laser module is reformed with a semi-reflective film. The light reflected from it is reflected again by the subsequent reflecting surface into a beam perpendicular to the original beam, and the light transmitted through the semi-reflective film deviates from the original incident direction by refraction, and in order to maintain the original direction, the surface of the spectroscopic film is plated. A wedge is fixed, and the angle of the wedge is selected such that the beam passes through the wedge to form a beam that is in line with the beam that is directed toward the pentagon. An automatic or manual level can be established using two sets of beam expanders and optical deflectors. In a first implementation of the invention, the fine light from the laser module is first directed toward the first beam expander. A portion of the incident light of the first beam expander expands into a first optical plane, and another portion passes through the expander holding direction toward the optical deflector and is deflected 90 by the deflector. A second optical plane is formed perpendicular to the first optical plane toward the second beam expander. In the above implementation, the first beam deflector must have the function of optical splitting at the same time: its splitting function divides the incident light into two parts, wherein -^ the knife's original direction is unchanged; the other part utilizes the beam expanding function. An optical plane that is perpendicular to the original incident direction. Expanding In the second implementation of the present invention, the thin "beam" emitted by the laser module can be first decomposed by the spectroscopic optical element into two bundles of light = light I

The beam &" 穿透 formed by penetrating the plane is vertical, and as described above, when the deflector 20 is driven to rotate in one axis, the planar light amplitude is scanned.

In the direction, in order to overcome this, the two angles shown as circle one c are 45.

The beam B 〇 and the deflected beam β Γ are mutually perpendicular to the optical deflector to change the vertical light splitting optical element.

然而同樣由於平板厚度t的影響，這兩束光也有一個平行平移距離e，為此，也可以如第二圖d的同附加的平面平行平板所產生的平移來抵消這個平行平移，因為在在這光學系統中使用有兩片相成9 〇度的平面平行平板，係作適當的組合即可以產生無偏移的光束B t，鍍分光膜3 7的平行平面平板35和平面平行平板36之間的夾角為45。，平板36 的出射平面3 9鍍以反射膜，入射光束β 0首先穿過平行平板 36射向平行平板35的分光入射分光膜37。由於其平板的厚度tl影響，其出射光束Bt，與之有一個平移距離el，當該光束Bt’透過分光膜37穿越透過平板35後，其出射光ϋ 又將為其厚度t的影響而反向偏回一個平移距離^，小心選擇平行平板35和36的厚度折射率以及取向，因平行平板36 的厚度所引起的出射光束Bt，相對入射光束B〇的偏離el，可為平板3 5的厚度所引起的偏離距離e所抵消，從而兩光However, due to the influence of the thickness t of the flat plate, the two beams also have a parallel translation distance e. For this reason, the parallel translation can also be offset by the translation produced by the same plane parallel plate of the second figure d, because In this optical system, two plane parallel plates of 9 turns are used, and a suitable combination can produce a non-offset beam B t , a parallel flat plate 35 of the plated light film 37 and a plane parallel plate 36. The angle between the two is 45. The exit plane 39 of the flat plate 36 is plated with a reflective film, and the incident beam β 0 is first passed through the parallel plate 36 to the split-light incident spectroscopic film 37 of the parallel flat plate 35. Due to the influence of the thickness t1 of the flat plate, the outgoing beam Bt has a translational distance el. When the beam Bt' passes through the spectroscopic film 37 and passes through the transillumination plate 35, the exit pupil will be opposite to the thickness t. To offset a translation distance ^, carefully select the thickness refractive index and orientation of the parallel plates 35 and 36.

The incident beam B 射 is directed toward the tapered surface along the axis. The circular expansion is formed by its reflection to form a light plane Be. The third b-picture shows a totally reflective optically transparent inner cone beam. The expander 60 has an optical incident plane 62, and is rotationally symmetric with the shaft 61.
