Explosive identification is a contemporary issue in air transportation security. In this work, a new approach is developed for using a portable photospectrometer with a selective sensitivity sensor, namely a photodiode, to detect and identify explosives. Explosive mixtures in natural objects are identified, and quantitative analysis with data display is achieved using photospectrometry. The new physical capability (photodiode) applied in the sensor enables spatial separation and selection of UV and visible waves with calculated spectral accuracy of 5 nm. The developed algorithm for contactless spectral analysis ensures photodetector operation without preliminary calibration. A new approach for passenger-friendly and secure airport security checks is developed. A narrow corridor (1.5–2m wide and 2–3m long) is equipped with sensor tents, and a specific wavelength laser beam generator remotely identifies explosives. The camera in the corridor captures an image of the suspect if explosive detection is triggered by the sensor array.
