Abstract
An imaging apparatus (10) adapted for imaging onto a photosensitive medium (160) in one of a number of selectable image formats. A telecentric print lens assembly (132) can be indexed to any one of a plurality of positions along the output optical axis for imaging in a specific format. The print lens assembly (132) can be manually indexed or can be moved by a focus mechanism (80) under the control of a control logic processor (24).
Claims23
An imaging apparatus for printing an image from digital data onto a photosensitive medium in one of a plurality of image formats, the apparatus comprising:
- (a) a light source for providing a source light beam;
- (b) a control logic processor for formatting the digital data according to said one of said plurality of image formats to provide formatted image data;
- (c) a spatial light modulator for modulating said source light beam according to said formatted image data in order to form an exposure image;
- and
- (d) a telecentric imaging optics assembly disposed along the output axis at one of a set of predetermined positions according to said one of said plurality of image formats, for directing said exposure image onto the photosensitive medium.
An imaging apparatus for printing an image from digital data onto a photosensitive medium in one of a plurality of image formats, the apparatus comprising:
- (a) illumination means for providing at least one source light beam;
- (b) logic processing means for formatting the digital data according to said one of said plurality of image formats to provide formatted image data;
- (c) image modulating means for modulating said at least one source light beam according to said formatted image data in order to form an exposure image;
- and
- (d) a telecentric imaging optics assembly disposed along the output axis at one of a set of predetermined positions according to said one of said plurality of image formats, for directing said exposure image onto the photosensitive medium.
A method for printing an image from digital data onto a photosensitive medium in a selected format of a plurality of image formats, the method comprising:
- (a) positioning a telecentric imaging optics assembly along the output axis at a position corresponding to said selected format;
- (b) forming an exposure image having said selected format by modulating a light source according to the digital data;
- and
- (c) directing said exposure image through said telecentric imaging optics assembly onto the photosensitive medium.
