摘要：The invention relates to a device for spatial modulation of a light beam of the
type including: a polymer dispersed liquid crystal (PDLC) element, comprising at leasttwo pixels distributed in a matrix with two pixelisation axes and that can be addressedindependently of each other using a system with at least two electrodes; optical meansfor reducing the sensitivity of the said device to polarisation of the incident light beam.According to the invention, the optical means comprise depolarisation means fordepolarising the incident light beam on the said PDLC element.
