Abstract

A two channel near infrared reflectometer was designed and fabricated using laser (814 nm and 751 nm) diodes and separate photodiode detector circuits. Because the isosbestic point of HbO2 and Hb is approximately 814 nm, the gains of each channel were equated at this wavelength. The device is designed to measure relative change of local cerebral blood volume, HbO2 and Hb concentration in an unknown sample volume.
