Of particular interest is an interview-style paper that concludes that for machine vision and web-inspection applications, cameras based on CCD technology are still the imagers of choice.CCDs and night visionwww.pacificsites.com/~brooke/ACCD.shtmlBrooke Clarke's Web site contains information about CCD and CMOS cameras, night-vision devices, scientific CCD cameras, frame grabbers, and software. Clarke references specific devices with Hotlinks so that readers can access technical data from independent manufacturers. Understanding imagerswww.pv-inc.comPixelVision (Tigard, OR) manufactures CCD-based digital imaging systems for the scientific, medical, industrial, and surveillance markets. In addition to describing the company's products, this site contains a number of technical papers that describe the types of imagers now available, their performance characteristics, and systems design and image-quality issues. As well, there are descriptions of applications including thermal imaging, astronomy, and confocal imaging, with links to cameras that can be used in such applications.

Bugeye/visionchips/vision_chips/vision_chips.htmlAlireza Moini's book, Vision Chips or Seeing Silicon, was developed at the department of electrical and electronics engineering of the University of Adelaide (Adelaide, Australia) three years ago. This lengthy work is invaluable for anyone wishing to study imaging devices. With descriptions of nearly every device ever developed, this site includes information and comparisons on devices ranging from Carver Mead's silicon retina to logarithmic sensors using MOS diodes.
