Abstract

Phase light modulator has been used in many underwater applications, such as turbulence mitigation, or laser beam shaping, to improve imaging and communication in the underwater environment. Liquid crystal on silicon (LCOS) or Liquid Crystal Display (LCD)-based phase light modulators are used in these applications. In recent years, Texas Instruments Digital Light Processing division developed a piston-mode Phase Light Modulator MEMS device (TI-PLM). One of the benefits of the device is its capability of supporting a high frame rate (i.e., 5.7kframes/sec). In this paper, we evaluated this TI-PLM device on an optical benchtop. While the main focus was the image quality of the Computer-Generated Hologram (CGH), the results also shed some light on this device’s capability for other PLM applications.
