Abstract

Remote controlled spatial light modulator (SLM) has been applied to design tuned "pin-hole" filter. The name "hole" means transparent area in the spatial light modulator (SLM) window. Transparent area in the SLM is remote controlled in the presented filter in accordance with the imposed "holes" distribution. As a result desired optical field diffraction has been obtained in the SLM window. Finally, one produces controlled movement of the focus in a resulting "pin-hole" filter. Proper optical field simulation has been described as well as presentation of the filter.
