Abstract
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.
