発明の名称 (英語) WAVELENGTH DETECTION TYPE OPTICAL SENSOR SYSTEM
発明の概要(英語) [Problem] To provide a sensor capable of achieving both size reduction and high accuracy measurement. [Solution] A wavelength detection type optical sensor system according to the present invention comprises: a plurality of wavelength variation type optical sensors (S1, S2) that has a Fabry-Perot optical resonator (FFP) onto which the light emitted from a light source is incident and an output frequency band reflecting filter (FBG) which emits output light with a reflection wavelength frequency band that includes the line spectrum output from the Fabry-Perot optical resonator; an optical circulator (CIR) which emits the light incident to a first terminal from a second terminal and emits the light incident to the second terminal from a third terminal connected to a wavelength detection means; a first light path that is formed by connecting a plurality of Fabry-Perot optical resonators in series from the light source with the end being connected to the first terminal of the optical circulator; and a second light path that is formed by connecting a plurality of output frequency band reflecting filters in series with the end being connected to the second terminal of the optical circulator.
