We propose a novel switchable circular-to-point converter (SCPC) device based on the holographic polymer dispersed liquid crystal (HPDLC) technology. An SCPC device converts the Fabry-Perot ring pattern into one point or point array, while an external electrical field on the SCPC will deactivate the conversion. By designing an Indium Tin Oxide (ITO) ring-pixel pattern on the SCPC that match the Fabry-Perot circular interference pattern, we are free to select different single rings of Fabry-Perot ring pattern and convert it into different points that is easy to be detected or collected. Stacking different single SCPC elements will give us a random Optical Switch with application in Lidar detection and optical telecommunication.
