Abstract
An optical image generator includes a spatial light modulator and a display device. The spatial light modulator contains a material whose optical property can be changed corresponding to a change in the image pattern of an electronic charge emitted from a photocathode, so that the image pattern can be written into the material. The display device contains a two-dimensional light emitting diode (LED) or a liquid crystal display of matrix type which is arranged against the photocathode of the spatial light modulator.
Claims6
An optical image generator, comprising:
- a spatial light modulator, said spatial light modulator including a photocathode and a crystal material whose optical property changes with the charge thereon, which can be changed corresponding to the change in a two-dimensional image pattern impinging on the photocathode, the spatial light modulator additionally including a microchannel plate between the photocathode and the crystal material;
- and
- a display device, said display device including a light emitting element matrix array controlled by a computer and arranged adjacent said photocathode.
