MULTIMODE STRUCTURE FOR CURRENT MEASUREMENT, ULTRASONIC AND NEAR-IR SPECTRUM COLLECTION AND PROCESSING

摘要

A compact device and method for collecting and processing acoustic and near-IR spectra of a bio-sample. The device (10) has a spectrometric unit (12) and, in proximity to an outer surface of the spectrometric unit, is a unit (14) for processing spectral data collected by the spectrometric unit. The spectrometric unit outer surface has: an acoustic energy transmission port and a near-IR radiation port for applying, respectively, acoustic energy and near-IR radiation to the bio-sample in the presence of a magnetic field; and electrode-terminal for measuring an electrical signal; an acoustic wave receiving port; and a near-IR radiation receiving port. The processing unit is preferably adaptable for performing at least one numeric operation on at least a portion of the data collected. The method includes: positioning an outer surface of a spectrometric unit nearby a surface of the bio-sample in the presence of a magnetic field; receiving acoustic waves and near-IR radiation with, respectively, an acoustic wave receiving port and a near-IR radiation receiving port; measuring an electrical signal with at least one electrode-terminal on the outer surface; and processing spectral data collected by the spectrometric unit.
