  • 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
    Moisture ingress in electronic packages can lead to catastrophic failures due to electromigration and corrosion. For space application, epoxy sealed CCDs are used, and the risk due to moisture ingress during test and storage rarely assessed. This article proposes a methodology to quantify
  • 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
  • Mass Effect: The Intertwined Future of CCD and TDI
    For most area and line scan imagers, CCDs are indeed history. But at the high end, where pristine imaging is required under low light, CCD continues to deliver what todayâ s CMOS imagers simply cannot deliver yet. Thatâ s going to change. Very often, change in one industry will shape the future
  • Application Note: AAT3190 Positive/Negative Bias Supply for CCD Camera Sensors
    Typical CCD camera sensors require a positive and negative bias voltage of +15V and -8V, respectively, at load currents up to 10mA. This application requires good output regulation for these bias supply voltages. In addition, CCD camera sensors are noise sensitive and require very low input
