Abstract

An interferometer is described in which a holographic diffraction optical element and a spatial spectrum filter system are used to transform a two-slit interference intensity distribution into a three-beam interference intensity distribution. This makes the measuring precision of two-beam interferometers as high as three-beam interferometers. The theory of this transformation and the making of the holographic diffraction optical element are described.
