1008446-US ABSTRACT OF THE DISCLOSURE A system for determining the range to an object utilizing a plurality of radiation responsive detectors arranged in groupings wherein a first grouping of detectors receives radiation from the object in a first pattern and the second grouping of detectors receives radiation from the object in a second pattern. The patterns move with respect to one another as the distance between the object and the system changes. The range is determined from a determina- tion of the relative position of the patterns by computing where the patterns will coincide if the focusing lens of the system is moved. The output is a signal having a character- istic indicative of the desired direction of motion of the lens and a charaeteristic indicative of the amount of such motion necessary to produce a proper focus condition.
