DEVICE FOR SPATIAL MODULATION OF A BRIGHT BEAM AND CORRESPONDING APPLICATIONS

摘要

The invention relates to a device for spatial modulation of a light beam of the type comprising: - a liquid crystal element dispersed in polymer (PDLC), said PDLC element, said PDLC element, said PDLC element comprising at least two distributed pixels according to a matrix having two axes of pixelation and which can be addressed independently of each other by means of a system with at least two electrodes; - optical means for reducing the sensitivity to polarization of the incident light beam of said device. Invention, the optical means includes depolarization means (74) for depolarizing the light beam incident on said PDLC element.
