Abstract

The system of remote control for the fiber optic grating interferometer is presented. The principle of operation is based on the opto-electronic method of introducing the carrier frequency into interferograms. A full automation of the measurement process has been achieved by using the system of the smart recognition of carrier frequency with a feedback into the laser diode driver. Due to the reduction of the interferometer elements, the possibility to measure in-plane displacement maps in locations with difficult access is introduced.
