S. Calixto et al., POLYMERIC GELS USED AS TRANSIENT RECORDING MEDIUM FOR INFRARED INTERFEROGRAMS, Infrared physics & technology, 36(6), 1995, pp. 1017-1024
Acrylamide based gels can record diffractive patterns and interferogra
ms when a CO2 laser (lambda = 10.6 mu m) is used as a light source. Si
multaneous recording in infrared and reading in the visible light may
be performed by sending coherent visible light to the IR photosensitiv
e medium. Spatial filtering can be performed to modify the final visib
le image.
