LED-transistor optical vascular measure: Replicability of a new device

We describe the use of a photo-optical device for the measurement of peripheral vascular activity, the Optek OPB707A, which we advocate to replace the now obsolete Sensor Technology STRT-850A. The Optek device provides a close coupling of light emitted and received through use of a GaAlAs light-emitting diode (LED). It also provides a photodarlington transistor as the receiver. The device should be used in a transmitted mode (e.g., LED illuminating tissue on volar surface of thumb and receiver on the thumbnail). Signal-to-noise characteristics and replicability of the signal from occasion to occasion are shown to be equal or superior to those of the earlier device.
