LIGHT DETECTION SYSTEM AND LIGHT DETECTION DEVICE

WIPO Patent Application WO/2018/054090

A1

A light detection system and a light detection device (100). The light detection system comprises a light source (10), a first aperture (20), a diffusion unit (30), a polarization conversion unit (40), an LCD panel (50), and a detection unit (60) sequentially provided along a light path. The light source (10) produces a light beam. Any unneeded light is blocked out by the first aperture (20). A useful light is diffused by the diffusion unit (30) then introduced into the polarization conversion unit (40), outputted as an S-state or P-state polarized light as required, and, with stray scattered light being further blocked out by a second aperture (80), is transmitted by the LCD panel (50) into the detection unit (60). The luminous flux of the light transmitted by the LCD panel (50) can be detected accurately, thus allowing increased accuracy in matching the efficiency of a light unit on the basis of the detected value of the light transmitted by the LCD panel (50). The light detection system solves the technical problem of an existing light detection system detecting inaccurate light brightness and inaccurate light unit efficiency, thus reducing a light detection process, and increasing detection efficiency.
