“…This is called polarization holography. The group of Prof. Ebralidze (Georgia) [19][20][21][22][23] developed a technique where they used dyed gelatin to record polarizing holograms. Azo-dye-colored gelatin films (methyl-orange, methyl-red, and other dyes) were prepared on glass plates.…”

Because this issue journal is dedicated to Gelatin here we present a few applications of gelatin in the field of optics. It is understood that optics is the science that studies the production, propagation, interaction and detection of light. Regarding the detection there are some materials sensitive to light (photosensitive) that are used like photomultipliers, CCD’s, crystals, two dimension (2D) materials and more. Among the 2D materials the most popular through several centuries has been gelatin based photographic emulsion that records spatial distributions of light. More recently (1970) films made of Gelatin with Dichromate (DCG) and dyes have been used. We describe some characteristics and applications of these two photosensitive materials. Also we describe examples where gelatin is used as Relative Humidity (RH) sensor and in the fabrication of optical elements based on gelatin. This article is intended to researchers outside the optics community.

“…To obtain a clear effect, it is necessary that the dye concentration in the solution is as high as possible. However, the high amount of dye concentration in solutions unconditionally leads us to self-induction of the dye molecules' aggregates in solid films, or leads to such state when aggregates are induced by light stimulation [2,[5][6][7][8][9][10][11].…”

“…In [8,10], in the gelatin film dyed by mixture of Chrisophenine and Acridine Yellow saturated water solutions, self induction of anisotropic micro particles ensemble has been realized; and there has been carried out a control of optical axes orientation and anisotropy integral area in this ensemble.…”

The anisotropy induction by light in self-induced molecular aggregations ensemble of azodyes has been studied. In the dynamic regime of anisotropy photoinduction the video-microscopy investigations of the film having photoinduced anisotropy in the crossed polarizers have been conducted. It is shown that image formation herein can be carried out in the way of light modulation of the granular anisotropy integral area of the film. According to an active light exposition, both the concentration and sizes of molecular aggregates having photoinduced anisotropy are being modulated.

“…For obtaining of more efficiency during the photoinduction of anisotropy, it is necessary that the dye concentration in solution is as high as possible. Nevertheless, the high value of dye concentration in solution surely leads us to self-induction of dye molecules aggregations in solid films, or to create such conditions when the aggregates are induced by the light-stimulation [3][4][5][6][7][8][9].…”

“…In the works [7,9] there is given that in gelatin film, dyed by the Chrisophenine and Acridine Yellow water solution mixed with 1:1 proportion and dried under room condition, the self-induced ensemble of molecule anisotropic aggregations was obtained. After its irradiating by the non-polarized active light the photodecomposition of aggregates was realized.…”

The work is dedicated to a study of anisotropy photoinduction during the light-stimulated molecular aggregations in organic compounds. The case of gelatin or polyvinyl films saturated by azo dyes is considered. By using the video and spectral techniques, the time-formation picture of optical image is studied. It is shown that in this case the image is formed in a similar way as in silver emulsions in the process of photographing-"with the grain distribution".
