Abstract

A multiple wavelength light spectrophometer for non-invasive monitoring of a body organ in vivo comprising: a single pulsed light source, optical fibers for transmitting to and receiving the infrared radiation from the organ, a radiation detector capable of branching received radiation into several different wavelengths, an amplifier, and a data acquisition system including a microprocessor capable of compensating for light diffusion effects by employing a specific algorithm.
