Spatial Light Modulator Principles

Download Principles Meadowlark Optics award-winning Spatial Light Modulators (SLMs) provide precision retardance control for spatially varying phase or amplitude requirements. Our SLMs consist of liquid crystal (LC) pixels, each independently addressed, acting as separate variable retarders. These SLMs are easily incorporated into optical systems requiring programmable masks and variable input/output devices. Applications include correlation, spectroscopy, […]

Geometric-phase microscopy (GPM) uses changes in the phase of light passing through biological specimens to yield high-resolution and high-contrast images, instead of relying on the attenuation of light used conventionally. Polarization optics and a spatial light modulator generate spatially variant polarization states of light that interact with the sample, creating a relative phase shift between transmitted and reflected light waves. By analyzing the phase information, GPM can reveal details not visible with other microscopy techniques. GPM is an effective non-invasive tool for live cell and tissue studies, with potential to enhance biological systems knowledge.
