Abstract
A novel moving corner-cube mirror interferometer (MCCMI) is presented. It has neither tilt nor shearing problems. It consists of one moving corner-cube mirror (MCCM), one fixed double-sided mirror (FDSM), one fixed plane mirror, and one beam splitter. The FDSM is a plane-parallel glass plate with both faces coated with high-reflectivity films. The effect of a FDSM tilt is analyzed. The optical path difference (OPD) is created by the straight reciprocating motion of the MCCM, and the OPD value is four times the displacement of the MCCM. The reflection characteristic of the corner-cube mirror (CCM) is analyzed by means of the vector expression, and the formulas of deviation angle of a CCM are derived. The effect of a MCCM deviation angle is analyzed. The new MCCMI is very suitable for high-resolution Fourier-transform infrared spectrometers used for atmospheric sounding.
