Paper Abstract

In this paper, a general scalar model to analyze the diffraction spectrum of holographic variable line space (VLS) plane grating at oblique incidence is proposed. The analytic expression for the diffraction spectrum of a VLS plane grating at oblique incidence with a parallel and uniform beam was obtained on the basis of Fraunhofer diffraction theory. And the applied scope of the analytic expression is that the grating period is much larger than the incident wavelength. Then some computing examples are given in the condition of single wavelength incident. This oblique incidence model can provide a theoretical reference for the real distribution of diffraction spectrum of holographic VLS plane grating. In future work, the diffraction efficiency and polarization state will be considered.
