Laser - Fibre Vibrometiy/Velocimetry Using Telecommunication Devices

摘要

We presented the next step of our research connected with development of the vibrometry/velocimetry based on fiber into free space radiation and heterodyne detection of scattered light. Some experimental configurations utilizing erbium doped fiber amplifier (EOFA) are presented. We propose two solutions of optical interface between the fiber system and an object.
