Based on the coordinate correspondence of the moving mirror
fixed mirror and interference surface in Fourier transform interferometer
the interference mode was analyzed under moving mirror tilted in several directions. In tilting status
a two dimension mathematical model of the interference plane was brought out
and the function of the interferogram was established. By analyzing the modulation depth
phase error and frequency noise
the error of the moving mirror were studied theoretically. It is found out that the different titling directions of moving mirror affect the system error independently
at the same time they can be added. The original phase of the interferogram is changed slowly or rapidly with the optical path difference changed
and the phase error is different too. Based on the error analysis
the max titling angle can be computed
two methods to keep adaptive alignment are also discussed.
