摘要
En 中文
We demonstrate a pyrometric contact-less temperature sensor using a flexible fused silica fiber of 360 mu m diameter able to measure down to 30 degrees C with a precision better than 1 degrees C at 10 Hz. Silica fibers, as opposed to dedicated mid-IR fibers, are non-degrading, low-cost, and bio-compatible. The large bandwidth (up to several kilohertz) and the broad temperature range (up to 235 degrees C) of the sensor can be instrumental for time-resolved analysis and control of laser ablation and electrothermal surgery procedures.
