  • Frame Transfer CCD
    is quickly transferred down the shift register and into the CCD's storage region, another integration period can begin. The storage region of the frame transfer CCD makes it faster and more expensive than the full frame CCD
  • CMOS or CCD for Machine Vision
    CCD imagers were the first products in machine vision and have led the industry for many years. However, CMOS imagers are catching up quickly and are being implemented in many more applications than in previous years. When selecting an imager, a number of issues should be considered, relating both to
  • CCD Test Methods
    will be given for performing these tests yourself. It is recommended that you familiarize yourself with the other subjects in CCD University before reviewing the subject of testing. These tests are important indicators of camera quality and they fulfill the commitment we have to our customers
  • CCD vs. CMOS
    Much has been written about the relative advantages of CMOS versus CCD imagers. It seems that the debate has continued on for as long as most people can remember with no definitive conclusion in sight. It is not surprising that a definitive answer is elusive, since the topic is not static
  • Guide to CCD-Based Imaging Colorimeters
    Selecting the right CCD-based imaging colorimeter for an inspection application requires understanding a few basic trade-offs in imaging colorimeter architecture. Proper selection of CCD, control electronics, filter, and lenses will help to ensure the optimal camera for a particular measurement
  • Moisture Ingress and Absorption in a CCD Package
    model is builtusing Fick diffusion laws, and taking into account the seal, the gas and each polymeric material inside the cavity. In the next step, the moisture concentration inside the cavity of the CCD package is monitored by means of humidity sensors throughout the experiment. Changing the moisture
  • View to the Future: CCD and CMOS Sensors Today and Tomorrow
    Digital image sensors are well established in private and professional applications. But which sensor type works best, CCD or CMOS? This question enlightens passionate discussions. A more detailed analysis reveals that these sensors share many common characteristics. Both CMOS and CCD can
  • Deep PCI Capture of Fast CCD Array Data
    A customer wants to digitize data from a 256x256 infrared CCD array. The array data is clocked at 4MHz through two output channels. Exactly two clock cycles occur between 12bit line signals, and a dozen or more clock cycles occur between successive frames. The customer wants to digitize the data
