Abstract

A new type of holographic optical element combines some of the flexibility of computer-generated holograms with the high light efficiency of volume phase holograms to produce optical elements capable of arbitrary illumination transformations with nearly 100% light efficiency. The optical element is recorded by subdividing a volume hologram film surface into numerous small areas (facets), each of which is individually exposed. A final optical system consisting of two dichromated gelatin holograms in series is demonstrated. The first hologram spatially redistributes the incident light, and the second hologram produces a desired phase front on the redistributed light.

  14. Light reflected from an object could be used for one of the recording waves. This standard holographic technique could work if the object were available and small. For larger complicated objects, for which we may also desire arbitrary illumination intensities, this technique would not be easy to implement. One particularly limiting factor is that the high exposure levels required by efficient hologram materials such as dichromated gelatin coupled with the relatively weak light reflected from diffuse objects would mandate excessively long exposure times. The technique also would not work if λrecording ≠ λreadout.

  18. One could use an axicon to produce annular illumination; however, this is a special case where a conventional optical element could do our redistribution. We wish to treat the problem more generally.
