[0028] It should be noted that when the photosensitive target plate 331 on the photosensitive target assembly 33 receives the laser beam emitted from right to left, the photosensitive target plate 331 is made of high transparent material and has the function of laser beam penetration, so the light source sensing film group 332 can sense the light intensity, and the wall thickness of the right groove wall of the sensing film pasting groove 3312 is designed to be 2mm, so that when the laser beam passes through the right groove wall of the sensing film pasting groove 3312 made of transparent material, the refraction of light can be controlled within a controllable range, but the light energy will be slightly reduced, but the reflective coating on the light guide plate 3322 can effectively reflect the light and transmit it to the photosensitive element plate 3321, so that the photosensitive element plate 3321 can realize light sensing, and the photosensitive element plate 3321 is composed of high-precision area array CCD / CMOS sensors, which has high sensitivity to light, and through the circuit processing and algorithm known technology design of the photosensitive element plate 3321, the two-dimensional coordinate X / Y axis position of the light spot on the photosensitive target assembly 33 can be obtained.
