Abstract— A novel principle and simple technique of suppressing the speckle noise in images displayed by a laser projection system is proposed. Wave coherence in a laser beam and speckles are destroyed in real time when the beam passes through a single FLC cell where spatially inhomogeneous phase light modulation takes place due to special FLC material and an electrical pulse regime.
