摘要

We present an analytical and comprehensive optimization design for multilayer diffractive optical elements (MLDOEs) in infrared dual band for angular incidence. The diffraction efficiency of MLDOEs is affected by both wavelength and incident angle. Accordingly, the proposed optimization design considers comprehensive factors for its further design and evaluation. It can realize high diffraction efficiency and optimal microstructures of MLDOEs in dual band for angular incidence. By using numerical simulations, we demonstrate the modulation transfer function (MTF) at the cutoff frequency in an infrared dual-band optical system. It was found that such a design provides more accurate results, which helps achieve both higher MTF and smaller microstructure heights.
