Performance of a polarization-analyzing CMOS image sensor was improved by two kinds of technical approach. Based on the whole-angle on-chip polarizer approach, a polarization-analyzing CMOS image sensor with multiple polarization-analyzing pixel array sets was designed Using 0.35μm standard CMOS technology. The accuracy of polarization analysis was improved to σ=0.0022 deg. A performance improvement of the on-chip polarizer was also demonstrated by a new photosensor designed with 65 nm standard CMOS technology.
