The parallelism we have previously drawn between an interferometer and an equivalent optical system enables us to study both systems similarly. The constant contrast condition along the localization surface is equivalent to the condition of isoplanatism at the system image. As the sine condition is necessary for a system to be isoplanatic, a relationship we call the equivalent sine condition must hold if the contrast is constant. Some classic interferometers do not satisfy this condition and we here analyze the Michelson interferometer. Moreover, we find that, for the record of interference fringes to be a pseudohologram, this condition must be unfulfilled.
我们之前在干涉仪和等效光学系统之间建立的平行关系，使我们能够以类似的方式研究这两个系统。沿定位面的恒定对比度条件等同于系统图像处等晕条件。由于系统等晕需要满足正弦条件，因此如果对比度恒定，我们称之为等效正弦条件的关系必然成立。一些经典干涉仪不满足此条件，我们在此分析迈克尔逊干涉仪。此外，我们发现，要使干涉条纹记录成为伪全息图，此条件必须不满足。
