Abstract
The present disclosure provides a method and system for estimating the temperature of a working environment. Treatments that use laser and optical fiber technology may cause an undesirable increase in the temperature of a working environment. To that end, a laser source to generate light beams sensitive to a change in temperature can be generated and the temperature determined based on a distance between a distal end of the optical fiber and a target and the generated temperature of the sensitive light beam.
Claims20
An apparatus comprising:
- a light source, the light source arranged to generate a source light beam wherein a coefficient of absorption of the source light beam in a liquid medium is a function of a temperature of the liquid medium;
- a first detector arranged to measure an intensity of the source light beam;
- an optical component arranged to convey the source light beam to an optical fiber and to receive a reflected light beam responsive to the source light beam being directed at a target via the optical fiber;
- a second detector arranged to measure an intensity of the reflected light beam;
- and
- processing circuitry arranged to determine a temperature of a working environment based on the measured intensity of the source light beam, the measured intensity of the reflected light beam, and a distance between a distal end of the optical fiber and the target.
