The design of an integrated optic Michelson interferometer sensor for stress, temperature, and microdisplacement measurements consisting of a semi-asymmetric X-junction made by Ti in-diffused LiNbO3 waveguides is reported. The possibility of performing simultaneous measurements of strain and temperature is investigated, and different calibration schemes are proposed. Experimental results of displacement-only measurements show a 64% intensity modulation with 33-dB optical loss.

Abstract

The possibility of performing simultaneous measurements of strain and temperature is investigated, and different calibration schemes are proposed. Experimental results of displacement-only measurements show a 64% intensity modulation with 33-dB optical loss.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
