Evaluation of Er-doped silica fiber as IR-to-visible image converter

A novel concept for an IR-to-visible converter is based on the up-conversion, incorporating a pumping radiation with the wavelength in the near IR. The theoretical heat transfer predictions are followed by the experimental results whereby the fiber is maintained at a series of temperatures. Additionally, an IR camera (2003 CEDIP), sensitive in the spectral range from 8 μm to 12 μm, is being used to ascertain the converter feasibility for room temperature applications under laboratory conditions.
