Abstract

In Chapter 2, we discussed how to design some basic DOEs, such as binary phase gratings, amplitude gratings, and FZPs, as well as how to simulate their far-field diffraction patterns. In this chapter, the discussion has been extended to multilevel and grayscale DOEs. In the previous chapter, designing DOEs for generation of a few interesting phase profiles such as 2 x 2, 3 x 3 spots with desired intensity ratios were presented. In this chapter, we present the procedure for designing DOEs that generate any desired intensity profile using the well-known iterative Fourier transform algorithm (IFTA).
