Abstract

The holographic optical engine that is composed of a spatial light modulator (SLM), image sensors, relay optics, and a control computer performs an optimization of a computer-generated hologram (CGH) in an optical system. The CGH that generates two- and three-dimensional focusing spots are optimized before or during laser processing. Therefore, this method can compensate for static imperfections and dynamic changes in the optical system.
