Abstract :
The focusing property of thick chirped hologram PDLC gratings is investigated theoretically. Focal length´s formula for linearly chirped gratings is obtained by using Bragg condition. Diffraction efficiency dependence on incident angle in focus point is calculated numerically and enhanced bandwidth is observed.
