Title:
MEASUREMENT SYSTEM AND MEASUREMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2021/199796
Kind Code:
A1
Abstract:
A measurement system 10 comprises: an excitation light irradiation means 11 that irradiates a surface F of interest, on which a pressure-sensitive coating material or a temperature-sensitive coating material is applied, with excitation light; a light intensity detection means 12 that detects the intensity of light generated near the surface F of interest; and a derivation means 13 that derives the pressure or temperature on the basis of the result of detection by the light intensity detection means 12. The excitation light irradiation means 11 is configured so as to be capable of radiating excitation light in a plurality of irradiation patterns, in which the spatial intensity distribution of the excitation light when the surface F of interest is irradiated changes at different timings. Using the derivation means 13, according to a comparison of the light intensities detected by the light intensity detection means 12 in the respective irradiation patterns, a component that is not synchronized with the irradiation patterns is specified as the ambient light intensity of ambient light other than the emitted light produced by the pressure-sensitive coating material or temperature-sensitive coating material, and the ambient light intensity is excluded from the result of detection of the light intensity, whereby the intensity of emitted light produced by the pressure-sensitive coating material or temperature-sensitive coating material in the surface F of interest is specified, and a measured value of the pressure or temperature is derived.
