Embodiment Construction

[0021] The double-moving mirror interferometer includes a beam splitter, a fixed plane mirror, and two scanning plane mirrors installed in parallel on a common sliding part that can be moved linearly, that is, the first moving mirror and the second moving mirror, The first moving mirror and the second moving mirror are parallel to each other, and their centers are located on the same plane, and are fixed together by a rigid structure as a single moving part; the beam splitter and the plane mirror are orthogonal to the first moving mirror. The included angles between the mirror and the second moving mirror are all 45 degrees, and the centers of the beam splitter, the plane mirror and the first moving mirror and the second moving mirror are located in the same plane.

[0022] The incident parallel light beam is reflected and transmitted on the semi-reflective surface of the beam splitter, and is divided into two beams of light I and II with equal intensity. Through the beam spli...

Abstract

The invention relates to a double movable mirror interferometer which comprises a beam splitter, a fixed plane mirror and a first movable mirror and a second movable mirror which are arranged parallelly on a common sliding component which can be moved linearly; the first movable mirror and the second movable mirror are parallelly fixed together by a rigid structure as an independent moving component; the beam splitter and the plane mirror are mutually vertical and has an inclined angle of 45 degrees with the first movable mirror and the second movable mirror; optical path difference is generated by straight reciprocating motion of the two parallel plane movable mirrors and is four times of displacement (relative to zero optical path difference position) of the two movable mirrors. The interferometer has simple structure and low cost and is applicable to various high-resolution Fourier transform spectrometers in spectrum working areas.

Description

technical field [0001] The invention relates to an interferometer, in particular to a double-moving mirror interferometer applied to a high-resolution Fourier transform spectrometer. Background technique [0002] In the 1950s and 1960s, the Michelson interferometer was first applied to spectroscopic technology. It consists of a beam splitter, a fixed plane mirror and a scanning plane mirror; the moving mirror and the fixed mirror are orthogonal, and the beam splitter The angle between the beam splitter and them is 45 degrees; the angle between the beam splitter and the incident light is also 45 degrees. The performance of this interferometer mainly depends on whether the virtual image formed by the moving mirror and the static mirror on the beam splitter is strictly parallel. The biggest problem affecting the application of Michelson interferometer in Fourier spectrometer is the tilt of the moving mirror during the scanning process. We know that the tilt angle θ of the mov...
