A multi-parameter nondestructive in-situ detector for cross-border goods

Abstract

The invention discloses a multi-parameter non-destructive in-situ detector for cross-border goods, comprising a complete machine casing, an XRF detection module, a Raman detection module, a vacuum system, a sample bin, a power supply system, a micro control and The display module, micro control and display module are respectively electrically connected with the XRF detection module, Raman detection module, vacuum system and power supply system; the XRF detection module includes a high-voltage power supply, X-ray tube, X-ray focusing bending crystal, and silicon drift detection connected in sequence. The Raman detection module includes a near-infrared achromatic objective lens and a Raman detection module. The Raman detection module includes a differential Raman sub-module and a near-infrared Raman sub-module. The differential Raman sub-module and The near-infrared Raman submodule is coupled to the optical path by a spectral dichroic mirror. The invention integrates the XRF module and the Raman module into the integrated design of in-situ composite focusing, which can realize the anti-counterfeiting detection and detection of cross-border goods and the on-site rapid non-destructive detection of harmful substances.

Description

technical field [0001] The invention relates to the technical field of photoelectric detection, in particular to a multi-parameter nondestructive in-situ detector for cross-border goods. Background technique [0002] With the rapid development of my country's international trade, the types and quantities of customs clearance goods have surged, and port anti-smuggling and bulk commodity safety monitoring have put forward urgent needs for on-site, rapid, non-destructive, multi-parameter detection and identification technology and equipment for cross-border goods. In the current customs clearance inspection, goods with similar appearance often rely on the experience of inspectors to make judgments, and incidents of concealing and falsely reporting restricted goods and high-value goods often occur. The existing port supervision mode for laboratory inspection relies on Laboratory testing instruments, sampling-sample transfer-sample processing-detection-result reporting process is...

Problems solved by technology

X-ray fluorescence spectroscopy (XRF for short) is an elemental emission spectrum detection technology. Although it is used in the detection of cross-border goods, conventional XRF is less sensitive to light elements (C, P, S, Cl) and trace heavy metal elements. Difference
