Abstract

A method of sensing small displacements between two images of complementary chromaticity is described. An autocollimator that uses this method of detection has a pointing sensitivity that exceeds visual interferometric techniques. Two images of complementary chromaticity are superimposed and made to move in opposite directions in response to a test-mirror rotation. The resulting chromatic asymmetry enables experimental detection of setting errors of 1.5 s of arc for a 0.08-mm-wide test mirror. Analysis of image chromaticity when the source is a krypton-ion laser predicts setting errors one-sixteenth of those obtained by interferometry.
