RAMAN SPECTROSCOPIC DETECTION DEVICE AND METHOD FOR MONITORING DETECTION SECURITY THEREOF

摘要

A Raman spectroscopic detection device (100) and a method for monitoring the detection security thereof. The method comprises: emitting excitation light (11) by a light source (10) and guiding the excitation light (11) to a sample (1); collecting an optical signal generated by the sample (1) illuminated by the excitation light (11) and generating spectral data representing the optical signal; determining, in the spectral data, a first portion (P1) representing an excitation light (11) component in the optical signal and a second portion (P2) representing a Raman scattering component and a fluorescence component in the optical signal; calculating a first parameter indicating a magnitude of the spectral intensity and a second parameter indicating a fluctuation of the spectral intensity for each of the first portion (P1) and the second portion (P2); comparing the first parameters of the first part (P1) and the second part (P2) and comparing the second parameters of the first part (P1) and the second part (P2); and determining whether the sample (1) is a dark-colored substance on the basis of the comparison result.
