A lens can perform the Fourier transform! 🔍 This is the 4F system: the first lens converts an image into its frequency components, and the second lens reconstructs it. By adding an aperture at the Fourier plane, we can filter out high frequencies. #Optics #Physics #b3d

Diffraction through a single slit: As we narrow the slit, diffraction dominates, spreading light out, revealing its wave-like nature. Widen the slit, and the beam straightens up, its width starts to mirror the slit, just as expected. #physics #optics #fourieroptics #light #photonics #python
