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.
