A. Fimia et al., REAL-TIME MEASUREMENT OF DIFFRACTION EFFICIENCY IN HOLOGRAPHIC MATERIALS WITH NONLINEAR RESPONSES, J. mod. opt., 41(10), 1994, pp. 1867-1873
Holograms were recorded on photopolymerizable materials with nonlinear
behaviour and the diffraction efficiency changes taking place were an
alysed with light different from that used for the recording. A theore
tical model is proposed which explains with good concordance the exper
imental results, and which allows holography to be used as a spectrosc
opic technique for monitoring photopolymerizations.
