Optical Device for Detection of an Agent

Technology

Employing ideas from detector arrays and imaging devices, the invention is an optical device for determining the presence of chemical and biological agents in the environment. Using a combinations of resonators for agent reception, filtration devices and processing systems, the device can receive an agent from the atmosphere and determine its type from a catalogue of known agents. Due to its efficient design, the invention can be incorporated into a portable device reducing size, weight, cost and power requirements, compared to conversional designs. In addition, the invention can be integrated easily with imaging devices. 

Problem Addressed

Chemical and biological agents are a major problem for mass population centers, such as cities. Detection devices are requisite for determining the presence and type of known chemical or biological agents.   

Advantages

• Optical detection device can be incorporated into portable devices
• Easily integrated with imaging devices
