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.
