Abstract:

A shear interferometer is analyzed based on a double–exposure hologram formed with the help of a Galilean telescope. It is shown theoretically and experimentally that the spatial filtering in the hologram plane enables checking the telescope over the field. Spatial filtering in the image plane of a mat screen makes it possible to record the interference pattern characterizing the phase distortions introduced in the reference wave by the aberrations of the optical system forming it.
