Description

technical field [0001] The invention belongs to the field of optical assembly, and in particular relates to a system and method for realizing high-precision gluing of a Sagnac solid interferometer. Background technique [0002] The spatially modulated Fourier transform imaging spectrometer based on transverse shear interference avoids the technical difficulties caused by moving parts and scanning mechanisms, and has the advantages of high stability, high throughput, and real-time measurement of spectra. Transverse shear interferometer is the core and key component of spatially modulated Fourier transform imaging spectrometer, and its typical representatives are Sagnac interferometric transverse shear interferometer and Michelson interferometric transverse shear interferometer. Sagnac interferometric transverse shear interferometer adopts the structure of triangular common optical path, which is less affected by external vibration, airflow and other factors, and has strong an...
