  "term": "Time delay and integration clock",
  "field": "Industrial and trades",
  "definition": "A specialized clock signal used in Time Delay and Integration (TDI) charge-coupled device (CCD) cameras to synchronize the transfer of charge packets with the motion of an image across the sensor. As the image moves over the sensor's columns of pixels, the clock shifts the accumulated charge from one row to the next at the same speed. The clock frequency must be precisely matched to the line scan rate, which is determined by the velocity of the object being scanned.",
