IMAGING SYSTEM

摘要

An imaging system 1 comprises: an illumination light source unit 10 that emits an illumination light having a wavelength in a near-infrared range; an illumination optical system 20 that illuminates an observed object 90 with the illumination light emitted from the illumination light source unit 10; an imaging optical system 30 that guides as a physical body light the illumination light that has been illuminated by the illumination optical system 20 onto the observed object 90 and has been scattered, reflected, or refracted thereby; and an imaging unit 40 that has an imaging sensitivity in a wavelength band of a near-infrared range, receives, the physical body light arrived after being guided by the imaging optical system 30, and images the image of the observed object 90. The imaging unit 40 receives the physical body light after the light has passed through water and hemoglobin.
