Abstract
An optical head comprising an array of laser diodes (LDA) where each member of the LDA having a fast axis direction and a slow axis direction of beam divergence, a spatial light modulator (SLM), an imaging lens, and a Micro-Scramblers array (MSA) where each member of the MSA has exit apertures and each member of the MSA is associated with a member of the LDA for scrambling the light only in the direction of the slow axis of the member of the LDA. The optical head can be incorporated into an external-drum electro-optical plotter or a flat bed electro-optical plotter.
Claims19
An optical head comprising:
- an array of laser diodes (LDA), each member of said LDA having a fast axis direction and a slow axis direction of beam divergence;
- a spatial light modulator (SLM);
- an imaging lens;
- and
- a Micro-Scramblers array (MSA), each member of said MSA having exit apertures and each member of said MSA is associated with a member of said LDA for scrambling the light only in the direction of said slow axis of said member of the LDA.
An external-drum electro-optical plotter comprising:
- an optical head comprising
- an array of laser diodes (LDA), each member of said LDA having a fast axis direction and a slow axis direction of beam divergence;
- a spatial light modulator (SLM);
- an imaging lens;
- and
- a Micro-Scramblers array (MSA), each member of said MSA having exit apertures and each member of said MSA is associated with a member of said LDA for scrambling the light only in the direction of said slow axis of said member of the LDA.
A flatbed electro-optical plotter comprising:
- an optical head comprising
- an array of laser diodes (LDA), each member of said LDA having a fast axis direction and a slow axis direction of beam divergence;
- a spatial light modulator (SLM);
- an imaging lens;
- and
- a Micro-Scramblers array (MSA), each member of said MSA having exit apertures and each member of said MSA is associated with a member of said LDA for scrambling the light only in the direction of said slow axis of said member of the LDA.
A method of producing a plurality of writing spots on a photosensitive medium, comprising the steps of:
- i. providing an array of laser diode emitters (LDA), said LDA having exit apertures and each member of said LDA having a fast axis direction and a slow axis direction of beam divergence;
- ii. providing an array of Micro Scramblers (MSA), said MSA having exit apertures and each of said individual Micro Scramblers associated with one of said laser diode emitters for scrambling light only in the direction of said slow axis;
- iii. providing a spatial light modulator (SLM);
- iv. providing optical means for imaging the exit apertures of said MSA;
- and
- v. imaging the exit aperture of each of said Micro Scramblers on said photosensitive medium.
