Abstract

Ultra Violet (UV) induced fluorescence remains a core technique for the real time detection of biological aerosols. With this approach, the detection of an aerosolized biological event is based on the fluorescent and scattering signals observed from biological particles when exposed to one or more UV sources. In 2004, the Edgewood Chemical Biological Center (ECBC) initiated an effort to develop a low cost, small, lightweight, low power biological agent detector, identified as the TAC-BIO, based on this principle. Unlike previous laser based detectors, this program has capitalized on Semiconductor UV Optical Sources (SUVOS) being developed by the Defense Advanced Research Projects Agency (DARPA). Compared to the existing UV lasers, these SUVOS devices and their commercial counter-parts offered a means of achieving small, low cost, low power UV excitation sources. A general design philosophy of incorporating these devices with other low cost components has allowed ECBC to develop a detector that provides a credible degree of performance while maintaining the target size weight and power attributes. This paper presents an overview of the TAC-BIO and some of the findings to date.
