CDD DE series Xray Detectors
 
Cheyney are the innovators of Linear Diode Arrays for Xray detection. We now have more than 30 years of in designing and manufacturing Xray detectors.










It has the following features :
Control Commands
    Set Line/Integration period
    Zero diodes (set black level)
    Full range for diodes (set maximum white level)
    Set gamma law lookup table
    Start/stop scanning   
    Display raw (input) data
    Display normalised output data
    Display underlying zero, gain and multiplier data
    Histogram display of pixel grey levels
    Calculate noise for each pixel
    Display test pattern output
    Radiographic trigger setup

Notes

  1. Maximum speed is specified for active length up to 512 mm.
  2. Dynamic Range is defined as saturation signal/RMS noise, normal detector sensitivity.
  3. Digital interface has 16 RS-422 I/O lines for data, but user can select actual data to be 14,12,10 or 8 bits. The default value is 8 or 12 bits
  4. User can designate radiographic trigger outputs by specifying Window left, Window right and Threshold.
