The dynamic parts of a laser beam profile are often caused by distortions or noise from camera sources or optical distortions from dirty filters or beam splitters. These dynamics can be removed with low pass filters. BeamGage, Ophir's next-generation laser beam analysis software, contains a processing feature located on the Capture tab called CONVOLUTION. Convolution Matrix or Kernel image processing can be used as a smoothing or blurring feature to remove the fast changes or dynamics from the beam profile. Here's how. Data Smoothing
