摘要
根据菲涅耳公式,通过计算超广角萨尼亚克干涉仪各面的反射、透射系数,得出干涉仪的透射率、出射立体角,最后推导出光通量的具体表达式。代入改型萨尼亚克干涉仪两臂玻璃ZBaF17和QF14尺寸和折射率等参量,得出超广角萨尼亚克干涉仪的出射光强是入射光强的0.4397倍,立体角为1.7316×10-4sr,AΩ=0.4×10-4cm2.sr。
According to Fresnell＇s formula, the coefficients of reflection and transmission of every interface of super-wideangle Sagnac interferometer （SASI） are calculated. The exit solid angle and transmissivity are deduced, and the expression of luminous flux is derived. The luminous flux optical throughput is calculated with the parameters such as sizes and reflective index of glass arms of ZBaF17 and QF14 in a modified super-wide-angle Sagnac interferometer. The solid angle is 1. 7316×10^-4 rad, the emergent intensity is about 0. 4397 of incidence, with Af2 = 0.4× 10^4 cm^2 . sr.
