Summary of the invention
Fluorescence formula fibre optic thermometer is that a kind of light intensity of certain natural fluoresence material excited fluorescence emission of utilizing recently realizes thermometric, when temperature change, variation has also taken place in the intensity of its excited fluorescence emission spectra, be that fluorescence intensity changes with temperature, when measuring the change amount of fluorescence intensity, by Microcomputer Calculation, just can obtain tested temperature.It is a kind of novel optical fiber temperature measuring method, and it can realize the absolute measurement of temperature, and certainty of measurement is not subjected to the influence of measured body slin emissivity, has very high sensitivity and certainty of measurement in middle low temperature range.In example of the present invention, the fibre optic temperature sensor that we utilized is to have used fluorescent optical fiber temperature sensor, the emission luminescent material that it utilized is sulfuration dioxy two lanthanums, select spectral line to do fluorescence intensity measurement at 540nm and 630nm, these two residing wave bands of spectral line during with our thermotherapy employed 1064nm be different with the 808nm laser wavelength, so used laser can not cause error to the fluorescence optical fiber measurement during treatment.Owing to adopt the fine small probe of full gloss, it can directly enter in the human body with laser fiber and not account for too large volume, so the present invention makes full use of the little advantage of optical fiber volume, a kind of brand-new laserthermia instrument probe device that laser fiber and fluorescence thermometric optical fiber are connected as a single entity, it has overcome above-mentioned shortcoming, volume is little, and various surgical grade stainless steels can directly be passed through the housing contacts tumor, detect the true temperature of tumor site, for thermotherapy provides the temperature basis for estimation of science, improve the efficient of laserthermia.
