Home / Polarization of Elastic Modulator
Photoelastic Modulators (PEMs) are sophisticated optical devices that leverage the photoelastic effect to dynamically modulate the polarization of light. This effect involves inducing birefringence within an optical element by applying mechanical stress. Their ability to modulate light polarization at high frequencies has made them indispensable tools in various scientific and industrial.
