Biological agent environmental detectors designed for automated detection and discrimination between biological aerosols that may include hazardous agents (e.g., bacterial and/or virus pathogens) and nonbiological aerosols. These detectors use a sensor with long-range capabilities; the sensors typically consist of passive automated-scanning infrared and/or ultraviolet devices that can recognize distant (typically at ranges of one mile or more) agent clouds. The system works by comparing the background spectrum obtained by the detector with the information stored in a computer. Remote-sensing biological agent detectors are used in civil defense and military applications.
