摘要
通过对干涉选择调幅光谱仪(SISAM)扩展函数的计算、分析,可知在光谱扫描过程中,面光源的大小以及调制器的调制幅度应相应地随之变化,并得出这一变化的规律。
By caculation and analysis of a family of spread functions of the new type SISAM with a single grating,we found that the dimension of light source and the amplitude of modulation should be adjusted at the proper rate during the spectral scanning.
