Abstract:
A sensor (233) includes a first image pixel array (201) including first image pixels (P1, P2, P3Pn, 370) and a second image pixel array (251) including second image pixels (380). A polarization layer (355) is disposed between the first image pixels (P1, P2, P3Pn, 370) and the second image pixels (380). Scene light (339) incident upon the second image pixels (380) propagates through the first image pixels (P1, P2, P3Pn, 370) and the polarization layer (355) to reach the second image pixels (380).
