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
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.
