Patent ID: 7120482

Claim:
An optical measuring apparatus for irradiating near infrared light to a desired portion of an object to be measured, receiving arriving light from the desired portion and acquiring information about a predetermined substance present in the desired portion on the basis of analysis of data related to the received arriving light, said optical measuring apparatus comprises: a cover member removably attachable to the object to be measured; and a measuring unit provided on said cover member and including: at least one light irradiation section for directly irradiating the near infrared light to the surface of the desired portion of the object; and at least one light reception section for receiving the arriving light from the desired portion of the object, wherein, in a state where said cover member is attached to the object to be measured, said light irradiation section and said light reception section are positioned out of contact with the surface of the desired portion of the object, wherein said light irradiation section includes at least one optical fiber for passing therethrough the near infrared light, the optical fiber being mounted to a movable suprort that undergoes predetermined displacement during the irradiation of the near infrared light from the light irradiation section.
