Abstract
There is provided an inside observation apparatus of an endoscope and the like which can perform an inside observation for irradiating an illumination light to a minute area of a surface of an object (for example, a living tissue) having a light scattering property and detecting a back-scattered light of the illumination light, can increase a detected light amount by a simply and low cost configuration by making an area of a detection region larger than an illumination region, and can reduce a time necessary to detect an body (for example, a blood vessel) to be observed and detect a region deeper than a conventional region.
