  • MIRROR-ENHANCED MEMS-BASED SPATIAL LIGHT MODULATOR
    Publication number: 20230251548
    Abstract: A micromechanical systems (MEMS)-based spatial light modulator (SLM) incorporates a mirror to increase the travel path of light. Light incoming to the MEMS-based SLM is incident on a modulation element of a phased-array. The modulation element reflects the light to a mirror, which reflects the light back to the modulation element. The modulation element reflects the light reflected off the mirror out of the MEMS-based SLM. A dispersive element allows the light to be steered by changing a wavelength of the light.
