WAVELENGTH AND BANDWIDTH SELECTION FOR DIFFUSE REFLECTIVE SPECTROSCOPY BASED GINGIVITIS DETECTION

摘要

A system (100) for detecting tissue inflammation, and gingivitis specifically, including a light emitter (102); a diffuse reflective spectroscopy probe (107) having a source-detector distance between 300μm-2000μm; and a plurality of detectors (106, 108, 110, 112) configured to detect: a first wavelength that is less than 615nm and having a first bandwidth; and second and third wavelengths that are equal to or greater than 615nm and have second and third bandwidths, respectively, wherein the second or third bandwidth is greater than the first bandwidth.
