LIGHT RECEIVING DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18249759 titled 'LIGHT RECEIVING DEVICE
Simplified Explanation
The abstract describes a light receiving device with multiple photoelectric conversion element units.
- Each unit consists of multiple photoelectric conversion elements arranged in two directions.
- Each photoelectric conversion element includes a quarter wavelength layer, a wire grid polarizer, and a photoelectric conversion section.
- The photoelectric conversion elements in the first direction have the same fast axis orientation for their quarter wavelength layers.
- The photoelectric conversion elements in the second direction have different fast axis orientations for their quarter wavelength layers.
- The photoelectric conversion elements in the second direction have the same polarization orientation for their wire grid polarizers.
- The photoelectric conversion elements in the first direction have different polarization orientations for their wire grid polarizers.
Original Abstract Submitted
A light receiving device according to an embodiment of the present disclosure includes a plurality of photoelectric conversion element units. Each of the photoelectric conversion element units includes a plurality of photoelectric conversion elements, the photoelectric conversion elements being M×N in total number, with M photoelectric conversion elements arranged in a first direction, and N photoelectric conversion elements arranged in a second direction. Each of the photoelectric conversion elements includes a quarter wavelength layer, a wire grid polarizer, and a photoelectric conversion section that are disposed in this order from a light entrance side. The M photoelectric conversion elements disposed side by side along the first direction include the quarter wavelength layers that have the same fast axis orientation. The N photoelectric conversion elements disposed side by side along the second direction include the quarter wavelength layers that have different fast axis orientations. The N photoelectric conversion elements disposed side by side along the second direction include the wire grid polarizers that have the same polarization orientation. The M photoelectric conversion elements disposed side by side along the first direction include the wire grid polarizers that have different polarization orientations.
