Embodiment 1
[0036] Sample to be tested: Take 5g of nitroglycerin in a blue polyethylene plastic bottle with a thickness of about 1.1mm.
[0037] A Raman detection system that can penetrate packaging without damage, mainly composed of a laser light source, an external light path system, an internal light splitting light path system, and a photoelectric detection system, and the detection is completed through the control of a single-chip microcomputer.
[0038] Among them, the laser light source is composed of two lasers. The incident focus of the 1# laser with a wavelength of 785nm on the blue polyethylene plastic bottle is at the same position as the collection focus of the external optical path system, that is, △S=0; The position of the laser is such that the incident focus of 2# on the blue polyethylene plastic bottle is offset by a certain distance from the collection focus of the external optical path system, that is, ΔS'=8mm. The included angle of the incident beam is ω=45°; the time...
Embodiment 2
[0045] Sample to be tested: Take 5g of potassium nitrate in a white polypropylene bottle with a thickness of about 1.1mm.
[0046] A Raman detection system that can penetrate packaging without damage, mainly composed of a laser light source, an external light path system, an internal light splitting light path system, and a photoelectric detection system, and the detection is completed through the control of a single-chip microcomputer.
[0047] Among them, the laser light source is composed of two lasers. The incident focus of the 1# laser with a wavelength of 785nm on the white polypropylene plastic bottle is at the same position as the collection focus of the external optical path system, that is, △S=0; adjust the translation of the 2# laser with a wavelength of 785nm Position the laser so that the incident focus of 2# on the white polypropylene bottle is offset by a certain distance from the collection focus of the external optical path system, that is, ΔS'=6mm. The includ...
