Preliminary Laboratory Measurements of the Boss Modulation Transfer Function.

Abstract

A dual-input radiometer with matched modulation transfer functions is described. The two MTF's are defined by the form of the two entrance pupils, one of which is annular and the other of which is circular. The radiometer switches alternately between the two pupils by means of a set of polarizing components. By detecting only the resulting fluctuations in the image, the lower spatial frequencies in the object scene are suppressed. Preliminary measurements of the suppression characteristics as a function of spatial frequency are presented. (Author)
