Abstract

In the effort to reduce the potential risk of human exposure to chemical and biological hazardous material, the demand increases for a detection system which rapidly identifies possible threats from a distance to avoid direct human contact to these materials. In this scope, we present a novel detection system which is able to simultaneously measure spectrally and temporally resolved laser induced fluorescence signals excited by two consecutive laser pulses with differ-ent central wavelengths at 266 nm and 355 nm. The setup enables fast data acqui-sition that provides a complete dataset in less than a few milliseconds at repetition rates of 100 Hz. Furthermore, with its modular design it can be transported easily for operation at different locations. First measurements indicate a high perfor-mance and a good distinguishability of bacterial specimen within a limited set of three representative bacterial species. Together with the consecutive classification procedure, the setup promises to become a valuable tool for standoff detection of bio-hazards.
