INFRARED PRESENSITIZATION PHOTOGRAPHY.GEARY, JOSEPH MARTIN. January 1984 (has links)
Infrared presensitization photography (IRPP) is a double exposure technique that allows the recording of IR information on standard silver halide films not ordinarily sensitive in this long wavelength regime. This dissertation prescribes conditions for the practical implementation of the IRPP process in data collection. It then moves on to an investigation of mechanism, i.e., "why does IRPP work?" The study is divided into experimental and theoretical portions, with much heavier emphasis on the former. Experiments delve into the behavior of the characteristic and spectral sensitivity curves of film within the context of the IRPP phenomenon. The temperature rise experienced by the film during this process is determined. The influence of sensitizing dyes and ionic population increases in the grain crystals is also explored. Theoretical efforts concentrate on an extension of the Shaw photographic model to explain the IRPP effect in terms of a down-shifting in the overall quantum sensitivity requirements of the grain population.

Propagation and performance analysis for a 915 MHz wireless IR image transfer system / Propagation and performance analysis for a 915 MHz wireless infrared image transfer systemFelekoglu, Oktay. 06 1900 (has links)
A 915 MHz wireless IR image transfer system, comprised of an IR-160 Thermal Camera and MDS iNet 900 transceivers, was assessed for image transfer capabilities in different environments. Image transfer through natural and artificial obstructions, the capability of transferring images under urban environments, and an exploration of interference issues associated with RF communication links were investigated in detail. Concrete, wood, various construction materials, and building walls were examined to assess indoor propagation capabilities. Data transmission through random trees, buildings, foliage under various atmospheric conditions is also evaluated for outdoor system capabilities. A maximum free space range for acceptable IR image transferring is determined as 23 miles for line of sight (LOS). Non line of sight (NLOS) urban environment measurements revealed that urban path loss (15-60 dBm) is highly dependent on antenna orientation and obstruction geometry rather than the T-R separation distance.
