LEOK-44 Experiment Kit of Optical Image Addition/Subtraction

Features

  • Understand physical meaning of optical image addition/subtraction using grating
  • Understand Fourier spatial light filtering 
  • Acknowledge structure and principle of 4f optical system
  • Detailed instruction manual

Introduction

Image addition/subtraction is an optical operation in coherence optics, and it is a method of image recognition. This experiment kit employs a sine grating as the spatial light filter for the realization of optical image addition and subtraction. Through this kit, students can get a better understanding of the principles of optical image addition/subtraction, Fourier spatial light filtering, and 4f optical systems.
