Profilometry based on two-photon absorption in a silicon avalanche photodiode.

A novel profilometry method based on two-photon absorption in a silicon avalanche photodiode is proposed. This method has a wide dynamic range, from millimeters to tens of meters. The principle is experimentally confirmed with a fiber-optic Mach-Zehnder interferometer.
