Abstract
A 2D dynamic phase-modulating system (DPS) addressed by a digital signal at video frame rate can realize several optical transmission functions in the field of refractive as well as diffractive optics. Critical parameters are the space-bandwidth product, the phase shift and the light efficiency of the system. We demonstrate result of our current research activities on a compact system based on the SVGA spatial light modulator and a 635 nm laser diode. Points of discussion are limitations of pixilated diffractive optical systems, which cause boundaries for the application in the field of beam shaping and beam splitting. Furthermore, light efficiency and compactness of the systems architecture are main tasks. Examples are shown, which deal with the current state of beam shaping possibilities and which show the potential in the field of rapid-prototyping for optical transmission functions.
