摘要 | Collimation system provides collimated light for the static Fourier-transform spectroscopy (SETS). Its quality is crucial to the signal to noise ratio (SNR) of SFTS. In the present paper, the physical model of SETS was established based on the Fresnel diffraction theory by means of numerical software. The influence of collimation system on the SFTS was discussed in detail focusing on the aberrations of collimation lens and the quality of extended source. The results of simulation show that the influences of different kinds of aberrations on SNR take on obvious regularity, and in particular, the influences of off-axis aberrations on SNR are closely related to the location of off-axis point source. Finally the extended source's maximum radius allowed was obtained by simulation, which equals to 0.65 mm. The discussion results will be used for the design of collimation system. |
