  • CCD Technology
    CCD REVOLUTIONIZES TRIANGULATION DISPLACEMENT SENSORS. CCD TECHNOLOGY.  The “CURE” for the Common Triangulation Laser. Martin Dumberger. Technical Director. 3200 Glen Royal Rd. Raleigh NC 27617. ph: 919 787 9707. fax:919 787 9706. microepsilon@mindspring.com.             The twenty five year
  • 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
  • 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
  • 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
  • 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
  • Choosing High-Speed Surface Inspection Sensors - Comparing area CMOS to linear CCD for Speed, Cost, and Flexibility
    Traditional high-speed web or surface inspection has been reserved for linear CCD imagers, but today we also need to consider area CCD and area CMOS imagers. Each technology has different features that are best suited for a specific application. This article will discuss the differences between
