Abstract

A device and method for three-dimensional (3-D) imaging using a defocusing technique is disclosed. The device comprises a lens, at least one polarization-coded aperture obstructing the lens, a polarization-sensitive sensor operable for capturing electromagnetic radiation transmitted from an object through the lens and the at least one polarization-coded aperture, and a processor communicatively connected with the sensor for processing the sensor information and producing a 3-D image of the object.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A device for three-dimensional (3-D) imaging comprising:
 a lens;   at least one polarization-coded aperture obstructing at least part of the lens;   a polarization-sensitive sensor operable for capturing electromagnetic radiation transmitted from an object through the lens and the at least one polarization-coded aperture; and   a processor communicatively connected with the sensor for processing the sensor information and producing a 3-D image of the object.
