Paper Abstract
An imager that can measure the distance from each pixel to the point on the object that is in focus at the pixel is
described. This is accomplished by a short photoconducting lossi lightguide section at each pixel. The eye or
camera lens selects the object point who’s range is to be determined at the pixel. Light arriving at an image point
trough a convex lens adds constructively only if it comes from the object point that is in focus at this pixel.. Light
waves from all other object points cancel. Thus the lightguide at this pixel receives light from one object point
only. This light signal has a phase component proportional to the range. The light intensity modes and thus the
photocurrent in the lightguides shift in response to the phase of the incoming light. Contacts along the length of
the lightguide collect the photocurrent signal containing the range information. Applications of this camera
include autonomous vehicle navigation and robotic vision. An interesting application is as part of a crude
teleportation system consisting of this camera and a three dimensional printer at a remote location.
