Principle of Magneto-optic Spatial Light Modulators
An SLM is an electro-optic device that can modify the properties of a light beam in a controlled manner. The basic principle of an SLM involves the modulation of the refractive index or absorption coefficient of a material in response to an external electrical signal. Spatial light modulator (SLM) is a real-time programmable device for modifying amplitude, phase or polarization of optical wave front by electrically controlled signals. Our SLMs consist of liquid crystal (LC) pixels, each independently addressed, acting as separate variable retarders. The SPIE Digital Library offers a comprehensive collection of research articles, conference papers, and technical documents focused on spatial light modulators (SLMs), reflecting the breadth and depth of this rapidly evolving technology. They play a crucial role in various applications in optics and photonics, including beam shaping, holography, and optical tweezers.
