Davis Issued Patent for Agile IR Scene Projector

Minta Martin Professor of Engineering Christopher Davis (ECE/ISR), along with colleagues from the Johns Hopkins Applied Physics Lab (JHU APL), was awarded U.S. Patent No. 8552381 titled, “Agile IR Scene Projector.”

Davis worked with Raul Fainchtein and David M. Brown from JHUAPL on the project, which received patent on October 8, 2013. The abstract of the patent is as follows:

An infrared (IR) scene projector device includes a light emitter and a thermal emitter. The light emitter is configured to selectably provide visible light. The thermal emitter includes a vertically aligned carbon nanotube (VACN) array. The VACN array includes a plurality of carbon nanotubes disposed proximate to a thermally conductive substrate, such that a longitudinal axis of the carbon nanotubes extends substantially perpendicular to a surface of the substrate. The thermal emitter absorbs the visible light from the light emitter and converts the visible light from the light emitter into IR radiation.

Davis’ current research interests include optical and RF directional wireless, real-time advanced surveillance systems with “event” detection, the optical properties of nanostrcutures where surface plasmons can be excited, laser interferometry, dielectrometry, fiber sensors and biosensors, magnetooptics, optical trace detection, atmospheric turbulence, optical communication systems and devices, and studies of the biological effects of non-ionizingradiation.
