Title:
RAMAN SPECTROSCOPY FOR MINERALS IDENTIFICATION
Document Type and Number:
WIPO Patent Application WO/2021/034456
Kind Code:
A3
Abstract:
A method for identifying minerals and other materials illuminates a mineral with monochromatic light for an illumination duration and collects scattered light using a Raman spectrometer detector and an aggregated or average Raman spectrum data is determined. True Raman spectrum data is determined by subtracting a blank spectrum. The true Raman spectrum data is compared to reference spectrums to identify the mineral or material. A display or output of one or more of: (a) a name and/or chemical composition of one or more identified minerals; (b) the true Raman spectrum data; and (c) the one or more reference spectrums; are provided. The monochromatic light preferably has a wavelength in the range of about 400 nm to about 425 nm and the Raman spectrometer detector is adapted to detect a Raman-shift range of about 100 cm-1 to about 1400 cm-1.
