EXPANSION AND GENETIC TRANSDUCTION OF EBV-SPECIFIC CTLS

Not Available Differential absorption lidar (DIAL) systems have become extremely useful tools for remote sensing of atmospheric constituents. Physical Sciences Inc. proposes to develop a compact, lightweight, quantum cascade (QC) laser-based DIAL transceiver for remote sensing of airborne chemical compounds. The QC laser-based transmitter will facilitate ground and UAV-based monitoring of trace chemical vapors presently difficult or impossible to quantify using other laser sources. QC lasers are compact, solid-state devices which provide access to infrared wavelengths unattainable using CO laser-based lidars, greater ease of use than emerging IR lidar technologies, e.g. optical parametric oscillators (OPO), and have the potential to be as ubiquitous and inexpensive as diode lasers are today. The DIAL system described here will provide range resolved molecular column density measurements and 100% duty cycle data acquisition. A prototype DIAL system based on currently available QC lasers will allow remote quantification of chemical effluents relevant to NBC counter proliferation from unmanned aerial vehicle (UAV) platforms.
