ABSTRACT:
Phase holograms are recorded in the visible with high efficiency by the use of a transparent photosensitive recording composition containing a transparent thermochromic electrochromic or photochromic compound capable of forming a chromatic sensitizer temporarily in situ in the composition when under the influence of external physical excitation appropriate to the nature of the compound, namely heat, an electric field or irradiation. In the process of recording, the physical excitation is applied and maintained during the duration of the recording, whereafter the physical excitation is terminated and the recording composition becomes transparent again leaving the recording constituted solely by local refractive index variations.
