Fourier Transform in Optics

Week 4: Laplace and Fourier Transform

Fourier transform can be found on the Double Slit experiment performed by Thomas Young. The double slit experiment shows that light behaves like waves and not like particles. Fourier transform is involved because if a light passes through at slit, it will create a Fourier transform of the slits.
