Efficient Detection and Reduction of Noise from Near-Infrared (NIR) Sensor and Improving the Spatial Resolution in Nano Sensor Applications

摘要

Sustained progress has been made in the improvement of (NIRS) near infrared spectroscopy (NIRS) instruments and human tissue imaging. Recently, there has been growing interest in using the advantages of nanotechnology for outpatient of tissue oxygenation and hemodynamics monitoring. NIRS allows you to control muscle perfusion and oxygen saturation during contractions, which provides very good spatial resolution. The most commonly used approach for measuring NIRS signals is to use a pair of photo detectors and a near infrared LED. A NIRS wireless scheme with a stretchy optical sensor, suitable for both muscle and brain measurements, to provide an absolute measure of tissue oxygenation (tissue oxygenation index (TOI)) and measure the style of changes in the concentration of oxyhemoglobin (HbO2) and deoxyhemoglobin (HHb)). The goal of this work is to provide superior performance for source recovery and suppression of NIRS signal artifacts.
