Abstract

In this paper we describe BioLert II, an ultraviolet laser induced fluorescence (LIF) biological agent monitor for detecting low concentrations of pathogens amid the ambient aerosol. BioLert II measures the fluorescence intensity and size of individual particles, and computes the Degree of Threat (DoT), an indicator of the likelihood that a particular threat material has appeared amid the recently sampled aerosol background. Performance is quantified using Receiver Operating Characteristic (ROC) curves, which plot the relationship among threat concentration, probability of detection, and false alert rate. We present BioLert II ROC curves for the detection of several simulated biological agents in an environment of interest.
