Apparatus and method for rapid detection of explosives residue from the deflagration signature thereof
First Claim
1. An apparatus for determining the presence of particulate from explosive materials, which comprises in combination:
- a heated surface for receiving the particulate maintained above the deflagration temperature of the particulate, wherein an ultraviolet signature is emitted from the deflagration of particulate thereon; and
an ultraviolet photodetector disposed such that the emitted ultraviolet signature is detected.

Abstract
Apparatus and method for rapid detection of explosives residue from the deflagration signature thereof. A property inherent to most explosives is their stickiness, resulting in a strong tendency of explosive particulate to contaminate the environment of a bulk explosive. An apparatus for collection of residue particulate, burning the collected particulate, and measurement of the ultraviolet emission produced thereby, is described. The present invention can be utilized for real-time screening of personnel, cars, packages, suspected devices, etc., and provides an inexpensive, portable, and noninvasive means for detecting explosives.
