diffraction efficiency of holograms

[Thomas]

I've seen a number of claimed results for various films and chemistries, but have never seen an explanation of the technique that the authors used for diffraction efficiency measurement. I can think of a number of ways of doing this, but I just wondered if there was a standard, reproducible method described somewhere.

I can write you about diffraction efficiency measurement. But for this recital need many place in our forum. I can write and send to your e-mail address. If you want, write me on my e-mail address:
