Problem: To provide a substance remote identification device capable of remotely identifying nonspecific substances such as harmful substances. Solution: A laser device 10 for irradiating a laser beam to the space to be irradiated, a wavelength conversion device 20 for converting the wavelength of the laser beam emitted from the laser device into a plurality of different wavelengths and emitting the same to the space to be irradiated, The object to be irradiated is identified based on the detection results by the collection and detection devices 30, 40, 50 for collecting and detecting resonance Raman scattered light by resonance Raman scattering from objects and the collection detection devices 30, 40, 50 A processing device 60, and a material remote identification device and method thereof. |
