Abstract

Nearly diffraction-limited laser beam in the laser communications is often to be evaluated by the interferometers. A series of wave fronts sensors are manufactured which are designed as over 500 millimeters apertures and three kinds of thickness of 50, 100 and 200 millimeters according to different need of shearing amount. They are suitable for measurement of diffraction-limited laser wave front or the larger aberrations. The plate and the wedge are the basic structures for the sensors which are shearing interference between the forward surface reflection and the backward. These simple plates will make the mechanical design and adjustment easier. The wedge of aperture-divided is so designed that the precision of measured wave front is higher than the full aperture design for that the error comes from the material and optical manufacture is reduced through compare the up part and the down part each other. The method is explained in detail in this paper. Some experiment interferograms are analyzed and the wave heights are deduced.
