• abstract: Previously demonstrated angle sensitive pixels (ASPs) have been shown to enable integrated digital light-field imaging in CMOS, but suffer from significantly reduced pixel quantum efficiency and increased sensor size. This work demonstrates ASP devices that use phase gratings and a pair of interleaved diodes to double pixel density and improve quantum efficiency by a factor of 4.
