LEOK-46 Experiment Kit of Optical Image Differentiation


  • Understand principle of optical image differentiation
  • Understand Fourier spatial light filtering 
  • Acknowledge structure and principle of 4f optical system  
  • Detailed instruction manual


This experiment kit employs an optical correlation method for the spatial differentiation of an optical image, so that the image contour can be outlined with an enhanced contrast. Through this kit, students can get a better understanding of the principles of optical image differentiation, Fourier spatial light filtering, and 4f optical systems.
