Description:

An optical platform has been set up, which can achieve the hologram recording and the measurement of the diffraction efficiency of grating. By adjusting the recording beam configuration and optimizing the ingredient, transmissive and reflective H-PDLC-based volume holographic gratings have been fabricated, of which the maximal diffraction efficiency are 69.3% and 36.7%, respectively.
