Valery Filippov, Vadim Makarov, Andrey Starodumov, and Yuri Barmenkov, "Remote Bi12TiO20-based fiber optic voltage sensor," in Advances in Photorefractive Materials, Effects, and Devices, P. Andersen et al., eds., in Vol. 27 of OSA Trends in Optics and Photonics Series (OSA, 1999), pp. 613-616.
A fiber optic voltage sensor based on Bi12TiO20 crystal is described.
The use of a special back-reflecting prism as a phase-retarding element is shown to improve
the temperature stability of the sensor. A comparison between the temperature
properties of the glass back-reflecting prism and that of a quarter-wave plate is derived.
The sensor demonstrates temperature stability of ±1.5% from -20°C to 60°C
and sensitivity of 0.145% per 1V RMS at 850 nm without using an additional
temperature control channel.
