makes it possible to measure both displace-
ment and phase, the Fotonic Sensor has
been chosen as the best instrument for this
type of analysis by measurement experts in
the U.S. and Japan.
MTI Fotonic Sensors have been used successfully in the computer
disk-drive, aircraft, microelectronics and automotive industries;
research laboratories; and universities.
