我们展示和评估一种新的轮廓术的基础上,一对不同波长的光学微波和双光子吸收过程中的光电探测器。通过使用具有0.1、1、10和100 m的路径长度差的光纤系统来确认操作原理。测量的准确度优于10/sup-4/,这与先前使用正交偏振光学微波的系统相当。
We demonstrate and evaluate a novel profilometry based on a pair of optical microwaves with different wavelengths and two-photon absorption process in a photodetector. The operation principle is confirmed by using a fiber-optic system with a path length difference of 0.1, 1, 10, and 100 m. The accuracy was measured to be better than 10/sup -4/, which is comparable to the previously demonstrated system using orthogonally polarized optical microwave.
