| 摘要 |
The present invention is a digital printer that comprises the novel combination of a two-dimensional light valve (34), a backlight (36) that illuminates the entire two dimensional light valve, a driver (32) coupled to the light valve (34), the backlight (36) and an outside source (33) of digital image data, an imaging system (38), and a photoreceptor belt (40). The digital data representing the desired image is fed into the driver (32) from an outside source (33). The light valve (34) is then set according to the digital data by the driver. Once the light valve is set, the driver signals the backlight to illuminate the light valve in the manner of a flash exposure. The image (42) produced is then focused by an imaging system onto the surface of a photoreceptor belt (40) - thus exposing and capturing a latent image. In another aspect of the present invention, very compact lenslet arrays are employed in lieu of traditional optics. This reduces the overall space requirements of the presently claimed digital printer - making it readily suitable for desktop application. <IMAGE> |
