ULTRA-COMPACT APERTURE CONTROLLED DEPTH FROM DEFOCUS RANGE SENSOR

摘要

The present application teaches an implementation of an ultra-compact range sensor based on aperture varying passive depth from defocus. An embodiment of the present application teaches a range sensor, which is a fast LCD matrix that allows the acquisition of a plurality of images with variable focal levels by changing the size of the aperture of a typical lens. The range sensor of the present application may be implemented in mobile devices or used in the construction of medical endoscopes able to perform depth recovery.
