Caption: To test the acoustic system's ability to detect the difference between different types of explosives, the researchers prepared non-explosive simulants of different types fo explosive, attached a plastic cap to simulate the casing. The sample was subjected to acoustic waves and a laser vibrometer was used to measure how the plastic cap vibrates in response.
