Abstract:
1. A light sensor comprising: a substrate having a surface; a photodetector formed in the substrate proximate to the surface, the photodetector configured to detect light and to provide a signal in response thereto; a first color filter disposed over the photodetector and configured to filter light in a first limited spectrum of wavelengths to the photodetector; a second color filter disposed over the photodetector and configured to filter light in a second limited spectrum of wavelengths to the photodetector; a third color filter disposed over the photodetector and configured to filter light in a third limited spectrum of wavelengths to the photodetector; and a transparent substrate disposed over the substrate, the transparent substrate including a diffuser configured to diffuse light incident on the diffuser and to pass the diffused light to at least one of the first color filter, the second color filter, or the third color filter.
