Paper Abstract

Dynamic alignment system (DAS) is used to correct the misalignment of moving mirror in Fourier Transform Infrared Spectrometer (FTIRS) of which both fixed mirror and moving mirror are plane reflectors. The detecting precision of dynamic tilting angle of moving mirror offers guarantees to the adjustment performances of DAS. In this paper, the noise tolerance of measuring precision of tilting caused by moving mirror are theoretically analyzed and tested. Experimental results show that tilting measuring accuracy is improved with adjusting methods according to the noise tolerance analysis.
