Abstract
An image capture system comprising an optical path length extender (OPLE) to direct the light having a first polarization through a first light path through the OPLE, and to direct the light having a second polarization through a second light path through the OPLE, the first and second light paths having different light path lengths. The image capture system further comprising an image sensor to capture a plurality of image portions at a plurality of focal distances.
