  • CCD Technology
    not present the serious problems of the past. The CCD element used is a digital pixelized array detector. It has 1024 discrete voltages representing the amount of light on each pixel of the detector. A CCD element detector can carry 1024 x 1024 pieces of light intensity information. With the help
  • Laser Triangulation Sensors
    , a digital (binary) interface or a digital display for processing. CMOS and CCD type sensors detect the peak distribution of light quantity on a sensor pixel array to identify target position, whereas, PSD type sensors calculate the beam centroid based upon the entire reflected spot on an array. Because

    of fast-. moving subjects and signal processing for real time tracking. Cameras for these application markets generally require. output of still image with low noise, high grayscale and high sensitivity. Currently, CCD and CMOS are the main technologies available for image sensor devices
  • Wall Shear Stress Measurements in Two-Phase Flow using PIV, an Optical Sensor, and Wall Pressure Transducer (.pdf)
    Doppler Velocimetry (LDV). A laser beam is passed through an. array of optical elements to obtain a divergent interference fringe pattern originated at the surface of the sensor and. extending into the flow (Gharib et al., 2001). The scattered light from the particle passing through the fringes
