Adaptive cross-correlation detector
for signals of optoelectronic reflective sensors
1L’viv National University, Ukraine;
Abstract. A soft- and hardware realization of optoelectronic intellectual sensor for
biomedical noninvasive studies based on the analysis of light reflected from living tissues
has been described. The main feature of the developed model is use of an adaptive cross-
correlation detector controlled by the digital signal processor. Algorithms and operating
mode of detector are defined by the type of particular problem to be solved and
conditions of measurements. The proposed model was tested to identify dynamic signals
in the following areas: pulsometer, evaluation variability of the cardial rhythm,
evaluation of blood saturation by oxygen.
Keywords: optosensor, reflective sensor, cross-correlation detector, plethysmograph,
pulsometry.
