Abstract
An instrument designed for physiological monitoring should be relatively inexpensive, take readings rapidly and be able to discriminate optical signals due to specific chromophores. A cw, broadband, multifiber system can potentially meet these requirements. The use of a steady- state light source rather than making time-resolved or frequency-domain measurements means that the system is relatively inexpensive. Simultaneous detection of signals from multiple optical fibers means that multiple measurements can be made simultaneously. By making broadband measurements it is possible to discriminate amongst the many chromophores which contribute the optical signal. We have developed a cw, broadband, multifiber system and are testing it in vivo. A possible application is noninvasive, optical monitoring of the brain which has the potential to be a real-time, noninvasive method for clinical monitoring as well as being a technique for studying fundamental aspects of brain function.
