Abstract

The invention relates to methods to improve SLMs, in particular to reflecting micromechanical SLMs, for applications with simple system architecture, high precision, high power handling capability, high throughput, and/or high optical processing capability. Applications include optical data processing, image projection, lithography, image enhancement, holography, optical metrology, coherence and wavefront control, and adaptive optics. A particular aspect of the invention is the achromatization of diffractive SLMs so they can be used with multiple wavelengths sequentially, simultaneously or as a result of spectral broadening in very short pulses.
