Abstract
In this paper, the Intensity function of reflected Fraunhofer diffraction by reflecting grating with right angle grooves has been derived in the cases of the normal incidence and unnormal incidence of rays and the ruled grooves deviated from right angles. The retrodiffraotion properties of the grating are also analysed and discussed according to the numerical results.
