Abstract

An illumination device irradiates a predetermined area with measurement light whose wavelength changes over time. A light reception device includes an optical sensor that detects diffuse transmission light of an object located in the predetermined area. The light reception device is structured such that the optical sensor receives a component of the diffuse transmission light through the object which propagates in a direction deviated from an optical axis of the measurement light.
