Title:
HIGH-RESOLUTION TEMPERATURE SENSOR BASED ON BUILT-IN LIQUID CAPSULE AND SPECTRUM VALLEY POINT
Document Type and Number:
WIPO Patent Application WO/2017/140146
Kind Code:
A1
Abstract:
A high-resolution temperature sensor based on a built-in liquid capsule (2) and a spectrum valley point. The high-resolution temperature sensor is composed of the built-in liquid capsule (2), a metal block (3), a vertical waveguide (4), a horizontal waveguide (5), two metal films (1, 6) and horizontal signal light (200). Broadband light or frequency sweeping light is adopted by the signal light (200). The liquid capsule (2) is connected with the vertical waveguide (4). The metal block (3) is arranged in the vertical waveguide (4) and is movable. The vertical waveguide (4) is connected with the horizontal waveguide (5). The temperature sensor has a compact structure and a small volume, and it is convenient for integration . And the sensitivity of the temperature sensor can reach -274nm/℃.
