Abstract:
1. An image sensing module, comprising: a package lid; a plurality of micro prisms disposed on said package lid and adjusting an incident angle of an incident light, wherein each of the micro prisms have an inclined angle that is a function of a first side, a second side, and a third side of the micro prism, and wherein each of the micro prisms are configured to deflect light with a chief ray angle entering the micro prism to an exit light which is parallel to a line normal to the third side of the micro prism; a plurality of photo sensors converting photo signals of said incident light into electronic signals; a plurality of micro lenses coupled to the plurality of photo sensors; and an intermediate layer separating the micro lenses and the micro prisms for increasing the refraction of incident light on the micro lenses, wherein the intermediate layer comprises one selected from the group consisting of silicon oxide, silicon nitride and silicon oxynitride.
