Paper Abstract

Because of the inherent structures, most common gratings always produce an unexpected loss of the input signal, which limits the use of gratings in many fields to some extent. Considering that, a design of grating with many periodical micro isosceles prisms is proposed. Based on the scalar diffraction theory, the transmittance is derived from the definition of an optical path when a parallel light passes through a singular prism element. And according to the multi-slit Fraunhofer diffraction, the expression of light intensity distribution for the prism grating on the frequency plane is deduced and analyzed by means of Fourier transform.
