Beam isolated Michelson interferometer for Fourier transform infrared spectroscopy

摘要

An enhanced Michelson‐type interferometer using two beam splitters and corner cubes has been constructed from readily available components. The interferometer is controlled by a microprocessor which also performs the Fourier transform. This instrument can be used in continuous or stepwise scan modes with signal averaging and can be configured for single or double beam (source) operation.
