抜粋

We show that 1 °C drift of laser temperature yields a strain error of ∼8 μϵ in Brillouin optical correlation-domain reflectometry. Under the assumption that the strain measurement accuracy is +/-20 μϵ (severe requirement), +/-2.5 °C drift of the laser temperature can be permitted for proper system operation. We prove this prediction by performing distributed strain measurements at different laser temperatures. Our results indicate that, if we allow a strain measurement accuracy of approximately +/-100 μϵ (or more), we can even remove the thermal control of the laser, leading to cost reduction and downsizing of the system.
