Trace detection and X-ray security inspection technology respectively serve as the “nose” and “eyes” of security applications, detecting explosives through “smell” and “vision” perspectives. Following decades of innovation and deployment, they are currently playing critical roles in the integrated aviation security solution. This study explores the prospective fusion of these two technologies for aviation security. Starting with basic technical principles and comparisons, considering security, efficiency, and passenger experience, the study examines industrial trends and discusses the bottlenecks of existing solutions based on standalone security equipment. Subsequently it elaborates the novel concept of fusing trace detection and X-ray computed tomography (CT) in security inspection. According to qualitative analysis and discrete event simulation, the study predicts the effectiveness of such fusion. The study further discusses the challenges faced in the development of an automatic trace detection system, elaborates on its concrete innovations and different methods of fusion, and envisions the trends of fusing multiple security detection technologies. According to industry reality, this study analyzes the domestic and international application prospects of this technology in aviation security from a rational and optimistic perspective, aiming to visualize a blueprint for technology developers and end users of security equipment.
