Utilization of thermal sensitization of photographic emulsions in recording of holograms

Thermal sensitization of photographic emulsions was used to record holograms in the infrared and submillimeter parts of the spectrum. Photographs were recorded on a FT-101 specialist film using CO₂ laser radiation and were reconstructed using He–Ne laser radiation. The results demonstrated that thermal sensitization of silver halide emulsions could be used to record submillimeter radiation and in submillimeter holography.
