Abstract

Since continuous Time-Of-Flight ranging systems based on electrical mixing run into fundamental limits we designed an optical MEMS (de)modulator/mixer. With our dynamic (MHz range) subwavelength pitch diffraction grating we demonstrated TOF ranging with optical mixing.

用于光学混频连续飞行时间测距的动态亚波长螺距光栅调制器
由于基于电混合的连续飞行时间测距系统遇到了基本限制,我们设计了一个光学MEMS(解)调制器/混频器。利用我们的动态(MHz范围)亚波长间距衍射光栅,我们演示了光学混频的TOF测距。
