Title:
OPTICAL GAS SENSOR
Document Type and Number:
WIPO Patent Application WO/2017/104940
Kind Code:
A1
Abstract:
Disclosed is an optical gas sensor. The optical gas sensor comprises: a light source for emitting a light; a gas collecting unit having a cavity for receiving a gas to be measured; an optical waveguide unit for guiding the light emitted from the light source, outputting the light to the cavity, and allowing the output light to pass through the cavity of the gas collecting unit and then be re-output to the cavity; and an optical detection unit for detecting the light output by the optical waveguide unit. Therefore, the optical gas sensor can increase a light path exposed to a gas to be measured, in the cavity, so that the sensor can be downsized and can measure a gas having low concentration.
