Claim:
1. A device for three-dimensional (3-D) imaging comprising: a planar aperture mask having a central aperture on an optical axis and a defocusing aperture located off of the optical axis; a first optical filter for the central aperture and a second optical filter for the defocusing aperture, wherein the first and second optical filters are colored such that a background image produced by the central aperture is distinguishable from a defocused image produced by the defocusing aperture; a single sensor operable with the aperture mask to simultaneously capture the background image and the defocused image from an object; and a processor communicatively coupled with the sensor for processing sensor information and producing a 3-D image of the object.
