Chapter 7:
Computer-Generated Holographic Optical Elements
In earlier chapters, designs of simple binary, multilevel, and blazed DOEs using basic diffraction equations were presented. The proposed techniques were suitable for design of DOEs only for simple applications such as array generation, focusing, etc. On the other hand, DOEs generating arbitrary intensity profiles at the Fourier plane can be designed using the IFTA. In this chapter, an alternative method for beam shaping is presented using computer-generated holographic (CGH) optical elements. The design of simple to complex beam-shaping HOEs (holographic optical elements) is presented.
