Embodiment Construction

[0034] The invention described here belongs to the field of portable spectroscopy devices, spectrum identification systems, and client-server applications. The disclosed devices and methods take advantage of measuring and processing certain similarities in Raman and photoluminescence spectra. A properly designed spectroscopy system can be used to measure both Raman and broadband photoluminescence signals in a single excitation, and the difference between these two spectral characteristics, Raman and photoluminescence, affects the processing stage. Using a computer program based on some preliminary knowledge of the spectral properties of various organic and inorganic substances, the photoluminescence signal and Raman signal of the measured substance can be divided into two components, each of which is attributed to the photoluminescence scattering of the measured substance Content or Raman scattering content. The photoluminescence content of the measured spectrum can be compare...

Abstract

An apparatus and method for detecting Raman and photoluminescence spectra of a substance and identifying said substance by Raman and / or photoluminescence spectral characteristics of said substance are disclosed. An apparatus comprises a replaceable laser source aggregate with a laser source, a collimating system, a socket for receiving said replaceable laser source aggregate, while ensuring the operation of said apparatus with no further adjustment of a positioning of said collimating system or said laser source, a filtering system, a light dispersing system optimized for a spectral resolution and a spectral range sufficient to simultaneously obtain Raman and photoluminescence spectra of said substance, a detector, and at least one controller for processing electrical signals. The disclosed and claimed method provides for obtaining Raman and photoluminescence spectra of a substance simultaneously, for separating said spectra into components based on Raman and photoluminescence contents, for analyzing said Raman and photoluminescence contents, and for identifying said substance by utilizing a set of spectral processing methods.
