LIGHT-SENSITIVE DEVICE WITH MULTIPLE DEPTH OF FOCUS, SYSTEM, METHOD OF EXPANDING DEPTH RESOLUTION OF FOCUS AND OPTICAL IMAGING SYSTEM Russian patent published in 2017 - IPC H01L27/146 H01L31/18 

FIELD: optics.

SUBSTANCE: light-sensitive device with multiple depth of focus comprises two light-sensitive pixel layers. Wherein different light-sensitive pixel layers detect light signals with different colors. Two said layers are arranged with space so, that light signals from different distances and with different colors are focused on different light-sensitive pixel layers by lens.

EFFECT: technical result consists in creation of light-sensitive device with multiple depth of focus.
