[Using the statistic preprocessing method to raise the measurement accuracy of dynamic spectrum].
The development of the non-invasive measurement of blood compositions by near-infrared spectroscopy has attracted significant interests in recent years. But it has not yet been applied to the clinical field except the oximeter. The most important and difficult problem is that the instrument accuracy does not meet the requirement of the non-invasive measurement of blood compositions due to the effect of the individual discrepancy and complicated measurement conditions. So how to reach the instrument accuracy required is its key part. Based on the dynamic spectroscopy, a new non-invasive measurement method of blood compositions is presented, where the measurement accuracy is raised through the outlier eliminating and the assembly average of several measurement results. It has been proved by the experiment that the measurement accuracy can be raised by the outlier eliminating and the assembly average of several measurement results.
