FIELD: physics.
SUBSTANCE: optical system is meant for varying the shape of a surface on which an image is perceived, and has first and second spaced-apart partial reflectors, at least one of which is selectively switchable between a non-flat first shape and at least one second shape different from the first shape, and providing a light path for light incident on the first reflector. On said light path there is at least partial transmission of light through the first reflector towards the second reflector, at least partial reflection of light from the second reflector back towards the first reflector, at least partial reflection of light from the first reflector towards the second reflector, and at least partial transmission of light through the second reflector. In the display, the first reflector is placed between the display device for modulating light with the image and the second reflector.
EFFECT: transforming a flat or non-flat image to a non-flat or flat image.
