Paper Abstract

In the field of intersatellite communication, laser beam transmitted from the optical terminal is required to be highly collimated with diffraction-limit divergence. Then, the maximal wavefront aberration at the edge of exit pupil is about 0.3λ. In order to measure the diffraction-limit wavefront, we present a whole-field double-shearing interferometer based on double-shearing theory. In this paper, firstly, the principle and configuration of the interferometer is introduced. Then the theory of double shearing is discussed. At the same time, we extend the applications of the interferometer. Lastly, we present the simulations of interference fringes with different primary aberrations and give the experimental results for the measurement of diffraction-limit wavefront.
