Abstract:
Provided is an optical measuring device that can accurately distinguish between abnormalities due to optical performance and abnormalities due to problems in the configuration. The optical measuring device (2) comprises: a light source unit (22) that emits illuminating light on an object to be measured via an illuminating fiber (31); a first light reception unit (24) that receives, via a first light receiving fiber (32), returning illuminating light that is reflected by the object; and a calculating unit (291) that calculates the characteristics of the measurement history on the basis of a plurality of measurement values for diffused light based on illuminating light that is reflected by a reflection index member on which illumination light is to be emitted and is received by the first light reception unit (24) via the first light receiving fiber (32) and for diffused light based on light that enters from the outside and that is received by the first light reception unit (24) via the first light receiving fiber (32) and a diffusion index member through which light that enters from the outside passes through as uniform light.
