摘要：

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.
