A dual-mode polarization image sensor design based on in-pixel dual-band metal wire grid for trustworthy sensing

In this article, we present the design of an on-chip polarization image sensor with a hardware root of trust (RoT) for trustworthy sensing provided by an interconnection metal-wire-grid (MWG) structure using a standard complementary-metal-oxide-semiconductor (CMOS) process. The proposed MWG structur...
