The spectral DR non-contrast system uses a high-density detector with a pixel pitch of 0.8 mm, and each pixel can be subdivided into 128 energy channels, which can simultaneously collect transmission images and corresponding absorption spectral data. In the demonstration, the system completed the non-scan detection of 5 types of flammable and explosive substances, automatically obtained their transmission images in the whole process, and superimposed spectral line information to achieve rapid differentiation of different substance types. The high sensitivity and spatial resolution of the laser line array detector ensure clear spectral features can be extracted even in dense or overlapping samples.

With the high-precision recognition of absorption edge transitions and multi-channel data fusion algorithms, the system has shown broad application prospects in explosion-proof security inspection, criminal investigation and forensics, mineral resources exploration and other fields. The laboratory is promoting the engineering and on-site adaptation of this technology, with the goal of realizing online monitoring and real-time early warning, and providing one-stop, non-destructive, quantitative intelligent detection solutions for public safety and industrial monitoring.
