OPTICAL MEASUREMENT APPARATUS AND ENDOSCOPE SYSTEM

摘要

An endoscope system includes: an endoscope with a unit to be inserted into a subject and captures an inside image of the subject by an imaging unit provided in the unit to generate an image signal; an optical apparatus including a measurement probe to be inserted into the subject through the unit; an endoscope unit that switches between observation light of a plurality of wavelengths and outputs the observation light to observe a target object from the unit; a probe unit that outputs measurement light to measure characteristics of the target object via the measurement probe; a light unit that receives return light via the measurement probe, the return light caused by reflection and/or scattering of the measurement light on the target object; and a switching unit that switches a wavelength band of the measurement light to a different wavelength band from the observation light outputted by the endoscope unit.

1. An endoscope system comprising:
an endoscope which includes an insertion unit configured to be inserted into an inside of a subject and which is configured to capture an image of the inside of the subject by an imaging unit provided in the insertion unit and generate an image signal; an optical measurement apparatus including a measurement probe configured to be inserted into the inside of the subject through the insertion unit; an endoscope light source unit configured to switch between observation light of a plurality of wavelengths and output the observation light to observe a target object from the insertion unit; a probe light source unit configured to output measurement light to measure characteristics of the target object via the measurement probe; a light receiving unit configured to receive return light via the measurement probe, the return light being caused by reflection and/or scattering of the measurement light on the target object; and a switching unit configured to switch a wavelength band of the measurement light to a wavelength band different from that of the observation light outputted by the endoscope light source unit, wherein the light receiving unit comprises a spectroscope configured to receive and disperse the return light, and the switching unit comprises:
a computing unit configured to compute the characteristics of the target object based on results of dispersion by the spectroscope; anda control unit configured to switch a wavelength band of the return light used for computing by the computing unit in such a way that the wavelength band of the observation light outputted by the endoscope light source unit and the wavelength band of the return light used for computing by the computing unit are different from one another.
