Some More Aspects of the Michelson Interferometer with Cube Corners

Abstract

In the application of the Michelson interferometer for measurement of length by photoelectric methods there is a choice of either plane mirrors or cube corners as the end reflectors. In the present paper it is shown that the guide on which the moving cube corner moves needs to be only of moderate accuracy whereas it is known that the guide must be made very accurately when plane mirrors are used.
