Horizontal Lines or Patterns in Image
A faulty or irregular encoder signal may result in horizontal lines due to exposure time
fluctuations; ensure that your exposure time is regular. If you have verified that your
exposure time is consistent and patterns of low frequency intensity variations still occur,
ensure that you are using a DC or high frequency light source.
