Title:
OPTICAL SENSOR
Document Type and Number:
WIPO Patent Application WO/2013/073524
Kind Code:
A1
Abstract:
An optical sensor comprises a light source (10), an optical fiber (20) that is optically connected to the light source (10), an optical fiber bundle (40), a beam splitter (30) that splits light from the optical fiber (20) to the optical fiber bundle (40), and a light separation detector (50) that separates and detects light guided by the optical fiber bundle (40). The optical fiber bundle (40) comprises a plurality of optical fibers (41A, 41B, 41C, 41D, 41E and 41F). The optical fibers (41A to 41F) respectively have characteristic detection units (42A, 42B, 42C, 42D, 42E, 42F), the optical characteristics of which vary according to physicochemical state thereof.
