Speckle-interferometric camera for displacement measurements

  • P. A. Klumpp
  • E. Schnack


A simple setup of standard optical elements comparable to a shearographic camera can be used to record speckle interferograms with a fast lens. Rigid-body translations of the object are compensated for by a reference mirror attached to the object; the method requires only moderate stability and resolution of the storage medium (film). Interferogram reconstruction is possible with white light. Hence the method unites advances of different holographic and speckle-interferometric setups.
