Abstract
An image projection system for producing a projected image in response to electrical signals which represent the image to be projected. The projection system includes input capability to produce electrical signals in response to an image to be projected. These electrical signals are then transmitted to a light modulator which receives light from an external source. The light modulator consists of arrays of deformable mirrors which selectively deflect the light from the external source in response to the electrical signals received from the input capability. The deflected light is absorbed by opaque stops. The undeflected light travels through optics which form the projected image. A printer using this image projection system is also disclosed. The printer further includes the ability to develop the projected image in such a manner that the image is transferrable to a paper surface in a printer in such a manner that the image is reproduced upon the surface in a printer form.
