Portable instant display and analysis reflectance spectrometer

摘要: A portable analysis spectrometer (10) for field mineral identification is coupled to a microprocessor (11) and memory (12) through bus (13) A/D converter (14) display (16) spectrum of reflected radiation in band selected by an adjustable (20) filter (23). detector array (21) provides output signals at spaced frequencies within the which are simultaneously converted digital form display. The displayed compared with collection spectra known minerals. That stored selectively measured spectrum, or separate portfolio. In either case, visual comparison made. Alternatively, may use algorithm make comparisons search best match one identify target area.
