DOPPLER VELOCITY INTERFEROMETER

Photonics Spectra

lDOP The DVI 99 noncontact velocity recording system from Martin, Froeschner & Associates detects spontaneous changes in the frequency of light reflected from a moving surface. This turnkey system, which is housed in a 3-in. rack-mounted chassis, is connected to viewing optics via optical fibers and to a PC-based data acquisition and analysis system. The fast amplified photodiodes located in the data acquisition system can record changes in velocity with subnanosecond resolution. Unlike vibrometers, there are no limitations on maximum velocity or response time. Changes in surface reflectivity or in background light have no effect on the derivation of velocity. The system requires no calibration.
