Abstract

We present an idea to use optical vortex as a spatial light modulator (SLM) phase modulation depth marker. It can open a way to fast and efficient SLM calibration, which is required especially for SLMs that are able to change between introduced phase shift. Additionally, it may be used to control optical system aberrations and proper SLM phase shift, simultaneously. In this paper, the typical calibration method is discussed in brief. Next the new method based on vortex quality inspection is presented. The idea of the new method is preliminary verified in experiment, which is followed by a discussion of further research, that need to be done.
