SLM microscopy: scanless two-photon imaging and photostimulation using spatial light modulators [PDF]
Frontiers in Neural Circuits, 2008 Laser microscopy has generally poor temporal resolution, because of the serial scanning of each pixel. This is a significant problem for imaging or optically manipulating neural circuits since neuronal activity is fast. To help surmount this limitation, we have developed a "scanless" microscope that does not contain mechanically moving parts.

Fast-Response Liquid Crystal Phase Modulators with an Excellent Photostability
Crystals, 2020 We report a new mixture, which is modified from Merck TL-216, for liquid-crystal-on-silicon spatial light modulators (SLMs). To achieve 2π phase change at λ = 633 nm with 5 V operation voltage, the measured response time is about 3 ms at 50 °C. Meanwhile,

Positioning Accuracy in Holographic Optical Traps
Micromachines, 2021 Spatial light modulators (SLMs) have been widely used to achieve dynamic control of optical traps. Often, holographic optical tweezers have been presumed to provide nanometer or sub-nanometer positioning accuracy.

Displays Based on Dynamic Phase-Only Holography
Applied Sciences, 2018 Static holographic displays of high quality are works of art. We are creating commercial displays using dynamic phase-only spatial light modulators (SLMs). The main advantages of this approach are light efficiency and fault tolerance.
