SU70639A2 - The method of obtaining artistic images - Google Patents

Description

The MAIN copyright certificate no. 66964 describes a method for producing artistic images in a transparent plastic layer made up of films of bifold substance, such as cellophane, enclosed between two films of polyoid.

According to the present invention, to use a color pattern deposited on a film of a birefringent substance, as an illustration, the book is attached to the page of the book and examined in a light polarized with a flat reflective polarizer, for example black glass or plastic, through glasses with polaroids. whose planes of polarization are parallel.

To change the colors of the interference without rotating the polarizer or the analyzer, a rotatable, pattern-free plate of a pleochroism substance is placed between them, which is rotated to obtain the desired pattern color combination.

When examining an illustration, the picture is installed with its plane under some ghosts to the brilliant surface of the book page, perpendicular to the rays of light reflected from this surface at an angle of their maximum polarization. Rays of ordinary unpolarized light, incident on the black glossy or matte surfaces of a book reflecting them, at an angle of full or maximum polarization, are reflected to the film layer to a large extent directly polarized and with the direction of oscillation of the rays perpendicular to the plane of their incidence. and reflections and parallel to the plane of the birefringent layer. In the birefringent layer, each beam will in the general case turn into two polarized beams with mutually perpendicular directions of vibrations and different propagation speeds and some optical path difference will appear between these beams. In the gender analyzer reader points the rays will be reduced to one

oscillation planes and to interference. Some wavelengths of the spectrum will be destroyed by interference, some wavelengths in their amplitude or luminance are attenuated, some in their amplitude or luminance are enhanced, with the result that the white color in different parts of the layer, depending on the thickness of these parts, passed by rays of light, colored differently .

In order to obtain a color illustration of the changing colors of pleochroism in a layer glued together from several leaf films of transparent plastic painted with pleochroism (for example, from leaves of pleochroism colored cellophane), the figure is applied by engraving a thicker transparent film painted with pleochroism.

Observation of a change in colors in a pattern from one point is made by placing a plate of the same or another substance with pleochroism parallel to the leaves of the layer of the layer.

Glasses, framed in a cardboard frame and equipped with ribbons

to hold them over the eyes, they are placed in the pocket of the cover or binding of the book.

Claims (2)

1. A method for obtaining artistic images according to the author's certificate No. 66964, characterized in that for the purpose of using a color pattern coated on a birefringent substance as an illustration of a book, it is attached to the page of the latter and viewed in the light polarized by a flat reflective polarizer, for example from black glass or plastic, through glasses with polaroids, the polarization planes of which are parallel. 2. A method according to claim 1, characterized in that, in order to change the colors of the interference at will, without turning the polarizer or the analyzer, a rotary, pattern-free plate of a pleochroism having a pattern is placed between them, which is rotated to obtain the desired color combination drawing ..
