Embodiment Construction
[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0020] The present invention proposes a device for controlling the intermediate state of polymer dispersed liquid crystals, such as figure 1 As shown, it includes a laser light source 1 for testing, a chopper 2 and a half-mirror 3 arranged in turn on the propagation path of the laser light emitted by the laser light source 1 for testing, and a sample set under the half-mirror 3 Table 4, silicon photovoltaic cell 5, lock-in amplifier 6 for measuring the voltage of silicon photovoltaic cell 5, ultraviolet light source 8 for realizing photopolymerization, and computer terminal 7 connected with lock-in amplifier 6 and ultraviolet light source 8 respectively, chopping The device 2 is used in conjunction with the lock-in amplifier 6. The laser light emitted by the laser light source 1 for testing is incident on the half-mirror 3 after the chopper 2....
