Title:
ULTRA HIGH-RESOLUTION TEMPERATURE SENSOR ON THE BASIS OF EXTERNAL LIQUID CAPSULE AND FIXED WAVELENGTH
Document Type and Number:
WIPO Patent Application WO/2017/140147
Kind Code:
A1
Abstract:
An ultra rhigh-resolution temperature sensor on the basis of an external liquid capsule and a fixed wavelength consists of an external liquid capsule (1), a metal block (2), a vertical waveguide (3), a horizontal waveguide (5), two metallic films (4, 6) and horizontally spreading signal light (200), wherein the liquid capsule (1) and the vertical waveguide (3) are connected, the metal block (2) is arranged in the vertical waveguide (3) and can move, the vertical waveguide (3) and the horizontal waveguide (5) are connected, and the signal light (200) employs a fixed wavelength. The superhigh-resolution temperature sensor has advantages of compact structure, small size and high resolution and can be integrated conveniently; the average temperature resolution of the sensor can reach 0.99×10 -9℃, and the highest resolution of the senor is 0.595×10 -9℃.
