PHOTOSENSOR AND TERMINAL DEVICE

A photosensor (10) and a terminal device (100). The photosensor (10) comprises at least one photosensor sub-module. Each photosensor sub-module comprises a first photodetector (11), a second photodetector (12), a first linear polarizing plate (13), a second linear polarizing plate (14), a first phase delay film (151), and a second phase delay film (152). The first photodetector is for acquiring a light intensity of a first mixed light of a mixed light that has passed through the first phase delay film and the first linear polarizing plate, and the second photodetector is for acquiring a light intensity of a second mixed light of the mixed light that has passed through the second phase delay film and the second linear polarizing plate, wherein the mixed light comprises a first light beam (A) and a second light beam (B). After the mixed light passes through the second linear polarizing plate, a first light beam is filtered such that a difference between the light intensity of the first mixed light and the light
