Optical Chopper Based on Polymer Dispersed Liquid Crystal Gratings
The fabrication process of holographic polymer dispersed liquid crystal (H-PDLC) and its characteristics are introduced. Optical chopper based on H-PDLC gratings is put forward and experimentally conducted. The specific electrical driving source and controlling system are specially designed for H-PDLC based chopper. The one-channel and two-channel optical choppers based on H-PDLC gratings have been experimentally researched. According to experimental results, the new device proposed enjoys benefits such as rapid response, being without moving parts, being easy to be operated and integrated etc. The convenience of changing its frequencies and duty ratio is its biggest advantage over mechanical ones, which promises the new device has a good application prospect.
