Computer-generated holograms [PDF]
Photoniques, 2017 Diffractive optical elements (DOEs) have many advantages over conventional ones. For a start, they are generally lighter, take up less room, and have a wider variety of properties. They can also be used to fabricate hybrid elements that modify polarization, compensate for dispersion, and so on.

Nonplanar photolithography with computer-generated holograms [PDF]
Optics Letters, 2005 We outline a method for accomplishing photolithography on grossly nonplanar substrates. First we compute an approximation of the diffraction pattern that will produce the desired light-intensity distribution on the substrate to be patterned. This pattern is then digitized and converted into a format suitable for manufacture by a direct-write method ...
