According to researchers, the device's laser beam emits two pulses, one of which will resonate with the detected chemical in the explosive, and the other as a reference.
According to Marcos Dantus, a professor of chemistry at Michigan State University, "This device not only requires only one beam of light, but it does not require a bulky spectrometer, so it is really useful. It can quickly scan the human body and their luggage." Dantus Added, "it can not only detect explosive substances, but it can also show the exact location of chemical substances hiding, even if the target is only a trace of chemicals in the lighter." In addition, Dantus said that the device's laser will not It will be affected by baggage color or surface material.
In fact, this research and development of the University of Michigan was funded by the US Department of Defense, and its prototype equipment will be completed within one year.
