Abstract
A selectable view angle optical sensor is disclosed. The selectable view angle optical sensor comprises a substrate, a photodiode array disposed on the substrate, a first optical shielding modulation layer disposed on a first plane and a second optical shielding modulation layer disposed on a second plane. The first plane is on the photodiode array, the second plane is on the first plane, and the first and second planes and a top surface of the photodiode array are substantially in parallel. The dimensions and configurations of the first and second optical shielding modulation layers limit a field of view of the photodiode array so that the photodiode array has selectable view angle function.
