Patent ID: 6901284

Claim:
An optical measuring apparatus having a measuring device for optically measuring density or variation of an in-vivo metabolic material of a sample, comprising: a pair of a first irradiation part for applying a light beam on said sample and a first detection part provided corresponding to said first irradiation part so as to detect said light beam through said sample, wherein a first measuring position is obtained as substantially a mid point between said first irradiation part and said first detection part; a pair of a second irradiation part for applying a light beam and a second detection part provided corresponding to said second irradiation part so as to detect said light beam through said sample, wherein a second measuring position is obtained as substantially a mid point between said second irradiation part and said second detection part; a first display window for displaying representations of said first and second irradiation parts, said first and second detection parts and said first and second measuring positions corresponding to positions thereof on said sample; and a second display window for displaying respective time-series graphs of measurements of said in-vivo metabolic material of said sample corresponding to said first and second measuring positions displayed on said first display window.
