  • Page 30: How To Calibrate The Camera

    The calibration algorithm is performed in two steps. The fixed offset (FPN) is determined first by performing a calibration without any light. This calibration determines exactly how much offset to subtract per pixel in order to obtain flat output when the CCD is not exposed. 03-32-10091-04 DALSA...
  • Page 31 Dark calibration is used to remove the fixed analog offset from the video path. It is recommended you repeat the calibration when a temperature change greater than 10°C occurs.

  • Page 42: Light Sources

    • LED light sources are relatively inexpensive, provide a uniform field, and longer life span compared to other light sources. However, they also require a camera with excellent sensitivity, such as DALSA’s Spyder2 camera. • Halogen light sources generally provide very little blue relative to IR.
  • Page 43 Example: An acquisition system has a 512 x 512 element, 10µm pixel pitch area scan camera, a lens with an effective focal length of 45mm, and requires that 100µm in the object space correspond to each pixel in the image sensor. Using the preceding equation, the object distance must be 450mm (0.450m). 03-32-10091-04 DALSA...
