Claim Text:
1. A method of imaging comprising; receiving an optical image from two viewing angles within a single lens at an image detector; converting the optical image into two images with orthogonally modulated patterns by amplitude modulating the optical image from a first viewing angle with a first Ronchi pattern and amplitude modulating the optical image from a second viewing angle with a second Ronchi pattern arranged orthogonally to the first Ronchi pattern, wherein the two images overlap and are received by the image detector; outputting a single signal representing a single frame comprising the two images received by the image detector; and distinguishably detecting the two orthogonally modulated images in the single frame by demodulation decoding the frame using a first orthogonal modulation to generate a first video signal corresponding to a first viewing angle and demodulation decoding the frame using a second orthogonal modulation to generate a second video signal corresponding to a second viewing angle.
