· ÁÖ       Á¦: "Novel adaptive receivers for Laser Ultrasonics"
· Length of talk: 45 minutes
· Abstract: 
   Lasers are quite effective in generating ultrasound, but until recently,
  receivers for the detection of laser-generated ultrasonic waves were
  not well adapted for practical applications.
  Most laser ultrasonic receivers use an interferometer for detection.
  Conventional interferometers suffer from loss of performance
  because they can not process speckled beams from rough surfaces.
  They also require path length stabilization for linear signal detection.
  In this talk, I will describe a new family of compensated interferometers
  based using photorefractive crystals as real-time holograms or
  as adaptive photodetectors.
  These receivers require no path-length stabilization and can process
  speckled beams with no loss in signal-to-noise.
  They can also compensate for dynamic wavefront distortions due to
  mechanical vibrations or turbulence in the propagation path.
  The receivers differ among themselves in their sensitivity,
  ultrasonic bandwidth and speed of compensation.
  Thus, each will find use for specific types of applications.
  I will describe the operating principles of these receivers,
  compare their performance and present data on their use 
  in a variety of applications.
