Adaptive cross-correlation detector for signals of optoelectronic reflective sensors

摘要

A soft- and hardware realization of optoelectronic intellectual sensor forudbiomedical noninvasive studies based on the analysis of light reflected from living tissuesudhas been described. The main feature of the developed model is use of an adaptive crosscorrelationuddetector controlled by the digital signal processor. Algorithms and operatingudmode of detector are defined by the type of particular problem to be solved andudconditions of measurements. The proposed model was tested to identify dynamic signalsudin the following areas: pulsometer, evaluation variability of the cardial rhythm,udevaluation of blood saturation by oxygen.
