Title:
TEMPERATURE MEASUREMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/038731
Kind Code:
A1
Abstract:
This temperature measurement device comprises a Fabry-Perot interferometer (101), a power source (102), and a light source (103). The temperature measurement device observes light that is emitted from the light source (103) and that is transmitted through the Fabry-Perot interferometer (101), thereby obtaining the temperature of a measurement environment in which the Fabry-Perot interferometer (101) is positioned. The light source (103) emits light (121), (122) toward the Fabry-Perot interferometer (101). In an embodiment (1), the light source (103) emits a plurality of lights (121), (122) having mutually different wavelengths, and obtains the temperature of the measurement environment in which the Fabry-Perot interferometer (101) is positioned according to the color of the light that is transmitted through the Fabry-Perot interferometer (101).
