Abstract
Electronic detector-array synthesis techniques provide fast, precise and accurate digital control of electronic zoom for electro-optical scanning systems. Exponentially-arrayed detector elements with binary-tree size-synthesis and size-interpolation, coupled with logarithmic size-control, offer optimum implementation efficiencies (hardware minimization). Alternative implementations offer different tradeoffs.
