Benton's Notes on DE
Benton's Notes on DE
I just found Benton's notes for his MIT course on holography, by accident. A bunch of books on my bookshelf for optical books fell over; Don't know if it was a Voice From Beyond (!), but the stack of notes fell over so that his notes on the diffraction efficiency of various grating profiles (his Chapter 6) was uppermost. Since there is a controversy about the functional form of the DE, I'll let Benton explain it. Interesting that he notes the Q factor to differentiate "thin" holograms from "thick" ones.
