title = "Upconversion based spectral imaging in 6 to 8 μm spectral regime",
abstract = "Spectral imaging in the 6 to 8μm range has great potential for medical diagnostics. Here a novel technique based on frequency upconversion of the infrared images to the near visible for subsequent acquisition using a Si-CCD camera is investigated. The upconversion unit consists of an AgGaS2 crystal and a 1064nm diode pumped solid state laser. A globar is used as mid-infrared illumination source. Acquired images contain both spectral and spatial information. Angle tuning of the nonlinear crystal is exploited to scan the phase match condition, which allows to cover the full spectral range of interest for the full field of view. Simulated images are created and compared with the measured images.",
