# BeamTuner cleans the laser beam without a WF sensor

In July 2013 OKO released the BeamDoctor  system  for the  beam quality optimisation. The system is based on the  BeamTuner software and can include any OKO deformable mirror. Using only the focal spot image, the software automatically, in a number of iterations,  optimizes  the control signals to the the deformable mirror, to compensate for the  static aberration. The BeamTuner includes: The BeamTuner software,  a deformable mirror with appropriate computer interface and drivers,  and  inexpensive CMOS or CCD camera for the focal spot sensor. The system also can be used to compensate aberrations of imaging systems,  using real-time image sharpness as the optimization metric.
