Research on realization of optical zoom system with low-voltage-driving liquid crystal lens

设计了变焦比约为3的光学系统，并进行了实验测试。极薄的玻璃基板用于制造3层LC透镜。大大提高了响应性能。在LC透镜中使用高阻层，可以将图像化电极与LC层之间的绝缘体厚度减小到约1μm。因此，实现了厚度约为200μm、电压低至3V的LC透镜。建立了以LC透镜为聚焦元件的光学成像系统。确定了分辨率和MTF等分析方法。

Optical system with approximately zoom ratio of 3 is designed and tested experimentally. Extremely thin glass substrates are used to fabricate an LC lens of 3 LC layers. The response property is greatly improved. Using a high resistive layer in a LC lens, it becomes possible decrease the thickness of the insulator between the patterned electrode and the LC layer to approximately 1μm. Consequently, an LC lens with approximately thickness as small 200μm and voltages as low as 3V is realized. Optical imaging system with an LC lens as a focusing element is setup. The method of analysis of the resolution and MTF, etc, is confirmed.
