根据全息聚合物分散液晶(H-PDLC)的电光特性,即在电场的作用下对通过H-PDLC的光束呈现“开”和“关”两种状态。设计了方波及正旋波调制的单通道及双通道H-PDLC斩光器。实验表明,H-PDLC斩光器频率稳定,响应速度快(最快可达微秒级),体积小易于集成,无噪音,同时通过计算机可灵活控制电场的频率,占空比,波形,达到智能调制光的目的。 According to the electro-optical properties of H-PDLC, the light beam passing H-PDLC shows “ON” and “OFF” under the action of electric field. A single-channel and dual-channel H-PDLC chopper with square wave and positive-phase modulation was designed. Experiments show that, H-PDLC chopper frequency stability, fast response (the fastest up to microsecond), small size and easy integration, no noise, while flexible control of the electric field by the computer frequency, duty cycle, waveform The purpose of intelligent modulation of light.
