An image processing method is proposed to realize polarizer-free imaging of liquid crystal lens. Images I(l) and I(nl) are captured sequentially in the lens and non-lens states of the LC lens, respectively, and are used to generate a final high contrast image. The proposal is tested by experiments. Clear and well focused images are obtained, even though no polarizer is employed in the imaging system.
提出了一种图像处理方法，以实现液晶透镜的无偏振器成像。分别在液晶透镜的透镜状态和非透镜状态下依次捕获图像I(l)和I(nl)，并用于生成最终的高对比度图像。该方案通过实验进行了测试。即使成像系统中未使用偏振器，也能获得清晰且聚焦良好的图像。
