Abstract
An image sensor for three-dimensional ('3D') imaging includes a first, a second, and a third pixel unit, where the second pixel unit is disposed between the first and third pixel units. Optical filters included in the pixel units are disposed on a light incident side of the image sensor to filter polarization-encoded light having a first polarization and a second polarization to photosensing regions of the pixel units. The first pixel unit includes a first optical filter having the first polarization, the second pixel unit includes a second optical filter having the second polarization, and the third pixel unit includes a third optical filter having the first polarization.
