Technical Evaluation Report
Abstract
Session 1, New Sensors and New Approaches, was NATO PfP (Partners for Peace) unclassified and started with a presentation by T. Apostolova on new ideas for tuning the wavelength response of detectors throughout the IR, and possibly into the terahertz region, using applied electric and magnetic fields and unconventional biasing methods. A device concept was also described for detecting the full polarization vector of the signal within a single pixel of a quantum well detector as well as a concept for cooling the detector directly on the chip, pixel by pixel. All these new ideas were oriented to support space situational awareness missions, while optimizing detector design. These advances will also reduce detector size, weight and eventually their cost and at the same time increase their reliability. Next H. Hovland presented a new technology utilizing image reconstruction techniques used in tomography. It was demonstrated how the addition of moving apertures can enhance the acquired images. The next presentation by K. Lukin described a new optoelectronic device enabling multiplication of carriers inside a multilayered semiconductor structure and outlined the possible design of such a device to be used as a solid state photomultiplier for detection of weak signals.
