Laser system for generation of colored three-dimensional images
A laser system for generation of three-dimensional (3D) colored images based on laser sources generating light at a plurality of wavelengths including basic color range (red, green and blue) that illuminate a two-dimensional display, at a given color range wherein a plurality of 2D images formed at different depths by image light impinges on a first optical element, with wavelength-sensitive focal length. All images of the given colored range are perceived by the human's eyes as a single 3D image of this color range. 3D images in red, green and blue that are formed at different positions, are fused by a second optical element, with adjustable focal length. As the light is switched between red, green and blue color ranges, the adjustable focal length is adjusted to compensate a change of the focal length of the first element, so the human's eyes see a fully colored 3D image.
