Abstract

The application of polychromatic illumination and color-coded pupil apertures in optical transfer function (OTF) synthesis is discussed. Specific attention is focused on the use of photographic film in incoherent processors employing color-coding for OTF synthesis. Film is used primarily to provide a permanent record of an optical system output distribution but, under certain conditions, can also be used to perform image subtraction required in some synthesis operations.
