ABSTRACT:
An in-vivo information measurement apparatus having an insertion part; a light projection unit, provided at a tip of the insertion part, irradiates an examination site with intensity-modulated light which is intensity modulated at a first frequency; a light receiving unit receives return light from the examination site; an optical detector detects return light; an in-vivo information calculation unit calculates in-vivo information for the examination site based on a phase shift between a modulated detection signal, a detection signal from the optical detector is modulated at a second frequency, and a reference signal having a difference frequency equal to the difference between the first frequency and the second frequency; and a position moving mechanism moves at least one of a position at which the intensity-modulated light is emitted by the light projection unit and the position at which the return light is incident on the light receiving unit.
