High Performance SWIR Imaging Cameras

Table 1: Common detector materials and their typical detection range within the VIS-IR wavelength regions. Above 1100nm, Silicon is transparent and therefore cannot be used to detect photons of these wavelengths, however many other materials do have photon sensitivity at these wavelengths and longer, see Table 1. The materials listed have been developed into detection systems which enable image...

Consistent cutaneous imaging with commercial digital cameras.

OBJECTIVE To demonstrate how to improve the reproducibility and accuracy of digital images of the skin taken with commercially available digital cameras by transforming them to a standard color space, sRGB. METHODS Our computer algorithm transforms digital images to the standard sRGB color space. It is based on a card with a number of color squares with known colorimetric properties that is i...

General Imaging Geometry for Central Catadioptric Cameras

Catadioptric cameras are a popular type of omnidirectional imaging system. Their imaging and multi-view geometry has been extensively studied; epipolar geometry for instance, is geometrically speaking, well understood. However, the existence of a bilinear matching constraint and an associated fundamental matrix, has so far only been shown for the special case of para-catadioptric cameras (consi...

Uncooled detectors for thermal imaging cameras

COMMERCIAL VISION SYSTEMS In the last few years thermal imaging has found its way into many more commercial applications. Most of these applications require a low cost product with an uncooled detector. These sensors image in the LWIR, or longwave infrared band (7 14 μm). Different types of uncooled detectors are available on the market. Since the infrared detector is the heart of any thermal i...
