达曼光栅是用于产生等强度光斑的一维或二维阵列的二元相位光栅。最近，达曼光栅由于其从单个激光源向光学逻辑器件阵列提供光功率供应的能力而变得令人感兴趣。我们在这里提出的达曼光栅的可行性研究，在其中我们考虑几个参数，是重要的光栅的计算和制造。作为这项调查的结果，我们得出结论，达曼光栅是有用的阵列尺寸高达约40 × 40点。在该尺寸以上，光栅的计算和分辨率的问题成为主导。
Dammann gratings are binary phase gratings that are used to produce a one- or two-dimensional array of equal-intensity light spots. Recently, Dammann gratings have become of interest for their ability to provide the optical power supply to an array of optical logic devices from a single laser source. We present here a feasibility study of Dammann gratings, in which we consider several parameters that are important for the computation and fabrication of the gratings. As a result of this investigation we conclude that Dammann gratings are useful for array sizes up to about 40 x 40 spots. Above that size, problems with the computation of the gratings and with the resolution become dominant.
