Experiment Kit of
Optical Image Differentiation
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.
Feathure
Understand physical meaning of optical image addition/subtraction using grating
Understand Fourier spatial light filtering
Acknowledge structure and principle of 4f optical system
