title: Optimum imaging method for optical data processors.
abstract: Several two-lens systems are considered for imaging an input record with specified magnification and focal lengths. Under certain conditions the total length of each setup from input record to image can be minimized (absolute). Alternately, limiting values of minimum length configurations are determined in the neighborhood of the open endpoints of a range of operation.
