Abstract
A cerebral function measuring apparatus houses a light detector in a package that can be set on the head of the subject examinee with light detection elements, amplifiers, and high voltage power supplies sealed in the package. Each amplifier and each high voltage power supply are united into one and covered with a high polymer material with high dielectric strength, and further enclosed by a metallic shield so as to be insulated. The high voltage power supply consists of a very small coil and an integrated circuit to generate a voltage required to drive the light detection element in the package. A removable and safe module type light detector is thus realized.
