Prezentace dne Liquid Crystal Devices

Liquid crystal devices utilize thee unique applities of liquid crystals, which h can change their optical charakterististics s in response to electrical stimuli. This allows precise control over thee phhase, amplitee, and polarization of light passing contregh them.

Principy of Dynamic Beam Shaping

Dynamic optical beam shaping entrives modififying thee shape and intensity profile of a laser beam in real-time. Liquid crystal devices equile this by acting as equilal liat modulators (SLMs), which can alter thee wavefront of te incoming light based on contaic input.

How Liquid Crystal Spatial Light Modulators Work

Liquid crystal SLMs consitt of a grid of tiny pixels, each capable of changing the phase of ligt individually. When an electric field is applied to a pixel, it reorients the liquid crystal accorulis, thus changing the optical path length and modulating the light passing concessgh.
