摘要
从理论上分析了一些引起傅立叶变换光谱仪信号调制度下降的原因 ,具体的就平面镜面形、偏振态、探测器横向位置偏移、平面镜倾斜、角锥反射镜顶点之间的横向偏移等作了一定的分析 ,得到了几个重要的公式 ,并就这些公式的用途作了简短的说明。
The causes of decreasing the modulation of the signal of Fourier transform spectrometer were analyzed from theoretical point of view. Specifically the decrease caused by the plane mirror, polarization effects, detector's lateral shift from the optical axis of the system, plane mirror's tilt and the vertex shift of one corner cube reflector relative to the other was analyzed, and some formulas were deduced and their usages were simply commented.
