Abstract

The invention discloses a high-stability rotating mirror interferometer which comprises a first beam splitter, a first planar mirror, a second beam splitter, a second planar mirror, an inclined mirror and an energy collecting mirror. The first planar mirror and the second planar mirror are arranged in parallel to form a parallel mirror set, the parallel mirror set is fixedly connected with a rotary shaft, a beam splitting membrane of the second beam splitter is parallel with the parallel mirror set, the second beam splitter is fixedly arranged between the first planar mirror and the second planar mirror, and the inclined mirror is provided with an inclined angle. By the adoption of a pair of the planar mirrors, it is guaranteed that incident light and emitting light are parallel, rotation of the pair of the planar mirrors guarantees autostability of a system, detection time is shortened, the system is simple in structure, and processing, assembling and adjusting difficulty and production cost are lowered.

Description

technical field [0001] The invention relates to the technical field of spectrum detection and imaging, in particular to a high-stability time-modulated double-beam interferometer. Background technique [0002] Fourier Transform Infrared Spectrometer (FTIR) is an instrument that uses light interference to measure the spectrum of a target. It has a series of advantages such as multi-channel, high throughput, high signal-to-noise ratio, and high accuracy. It is widely used in industry and agriculture. It has a wide range of applications in production, scientific research, environmental monitoring, food safety, aerospace remote sensing and other fields. [0003] The interferometer is the core component of FTIR, and the performance of the interferometer determines the quality of the measurement results of the instrument. At present, FTIR interferometers are usually based on Michelson interferometers and their deformation structures. The structure is usually composed of three par...
