Abstract

The principle of operation of an achromatic modulator or phase shifter is presented. Specific triangular configurations are described that consist of two base gratings and a vertex element which may be either a transmission-type hologram or an acousto-optic modulator. The application of this concept is illustrated by a generalized white light interferometer with very fine differential phase control and two separated, collinear output paths. The achromatic phase shifter is also shown to make an important improvement to the white light cosinusoidal transform hybrid. Two different configurations are presented.
