Optical somato-measuring apparatus
First Claim
1. Optical somato-measuring apparatus comprising, means for providing a transparent sheet positionable on the surface of a living object to be diagnosed, the transparent sheet having a refractive index approximating that of the object to be diagnosed, means for supplying through the transparent sheet at least two laser beams intersecting at a measuring point within the living object being diagnosed, and means for observing the scattered light from a diagnostic point appearing at a point on the transparent sheet that is different from the points of incidence of the laser beams.

Abstract
An optical apparatus for somato-measuring such as measuring of fluid velocity in a minute blood vessel by a laser Doppler microscope, comprises a laser supplying at least two laser beams through a transparent sheet provided on the surface of a living object to be measured, the transparent sheet having a refractive index approximated to that of the object in order to avoid reflected lights from the surface of the object and to measure necessary lights scattered by the internal part of the object.
