US 2006/0138103 A1 · Method and system for production of laser-induced color images which change characteristics during observation

Abstract

The present invention discloses a method and a system for production of laser-induced color images which are able to change their characteristics during observation. In particular, they can change brightness, hue and saturation of color for the whole image and for its separate fragments. These effects are provided by special processing of the color image and by the transformation of the image into superposition of several primary color images and its fragments. These primary color images and their primary color fragments are transformed into arrangements of points, at which laser-induced marks are produced. Special location of laser-induced damages inside a transparent material and controlled illumination of these damages provide creation of laser-induced color images with changeable characteristics.

Dependent claims

A system for production of color laser-induced images inside a transparent material by special processing of color image and multi-color illuminating of the said transparent material, comprising:

Computer graphic system for processing of a color image in accordance with a color model, for determination of optical characteristics for each laser-induced mark, and for creation of location of the said marks inside the said transparent material so that the said marks provide reproduction of correct color image without an internal crash of the said transparent material;
Apparatus for creating laser-induced marks with the predetermined optical characteristics at the predetermined transparent material points;
Means for multi-color illumination of the said laser-induced damages so that parameters of the illuminated light is controlled.

Method for producing laser-induced image, the fragments of which are able to change their color, optical and other visual characteristics as well as able to create motion effects by transforming of color image into special point arrangements and by controlling hue and saturated colors of external light used for illumination of laser-induced images comprising:

processing a color image and generating point arrangements so that they consist of points corresponding to both initial color image and its fragments which change their color, optical and visual characteristics;
locating points of the said point arrangements inside the said transparent materials so that the control of the light illuminated laser-induced damages produced at the points can be produced for the image and its fragments separately;
generating laser-induced marks at the predetermined transparent material points with needed characteristics so that internal crash does not arise;
illuminating laser-induced damages corresponding to the all point arrangements so that needed image fragments change their color and other needed optical characteristics.
