Optical device for displaying static or animated images in e.g. animation field, has angular irradiation unit for producing equal luminous energy irrespective of position of observer within available observation field

摘要

The device has a furniture piece (3), a screen (14), and a darkroom (23) that is arranged around the screen. A neutralizing unit is arranged to neutralize undesired beams of light output from all external surfaces of the device. The beams of light are provided from a set of reflectors. An angular irradiation unit is arranged in a homogeneous and regular manner around any point of physical images for producing an equal luminous energy irrespective of position of an observer within available observation field.
