Abstract
A light sensor is provided. The light sensor includes at least one light sensor submodule, and each light sensor submodule includes a first light detector, a second light detector, a first linear polarizer, a second linear polarizer, a first phase delay film, and a second phase delay film. The first light detector is configured to obtain light intensity of first hybrid light resulting when hybrid light has passed through the first phase delay film and the first linear polarizer, and the second light detector is configured to obtain light intensity of second hybrid light resulting when the hybrid light has passed through the second phase delay film and the second linear polarizer, the hybrid light includes first light and second light, and after the hybrid light passes through the second linear polarizer, the first light is filtered out.
