SPECTROMETRIC SYSTEMS AND METHODS FOR IMPROVED FOCUS LOCALIZATION OF TIME AND SPACE-VARYING MEASUREMENTS

摘要

PROBLEM TO BE SOLVED: To provide a system and method of dynamically localizing a measurement of a parameter characterizing a tissue sample with waves produced by a spectrometric system at multiple wavelengths and detected at a fixed location of a detector of the system.;SOLUTION: The parameter is calculated based on impulse response of the sample, reference data representing characteristics of material components of the sample, and path lengths through the sample corresponding to different wavelengths. Dynamic localization is effectuated by considering different points of a curve representing the determined parameter, and enables formation of a spatial map of distribution of the parameter across the sample. Additional measurement of impulse response at multiple detectors facilitates determination of change of the measured parameter across the sample as a function of time.;SELECTED DRAWING: Figure 8E;COPYRIGHT: (C)2018,JPO&INPIT
