Biological optical measuring apparatus and light detection module

A biological optical measuring apparatus, comprising:

• a light irradiation module for irradiating a light on an examinee;
• a light detection module for detecting said light irradiated from said light irradiation module and transmitted through said examinee;
• and
• a computing device for computing blood kinetics of the brain of said examinee from a detection result of said light detection module,
• wherein said light detection module includes:
• a first circuit having a high voltage power supply;
• a second circuit having a signal amplifying circuit;
• and
• a light detection element for detecting a light,
• wherein said first and second circuits and said light detection element are disposed in three dimensions in the order of said first circuit, said second circuit, and said light detection element or in the order of a second circuit board, a first circuit board, and said light detection element,
• wherein said first and second circuits are enclosed in a housing material,
• wherein said housing material has a hole for guiding a light irradiated from said light irradiation module and transmitted through said examinee to said light detection element, and
• wherein a terminal for supplying a power and a terminal for guiding a signal detected by said light detection element to external are exposed outside said housing material.
