Gyakorisági számítások

Számítás in Fourier optics typically contingvy computing the Fourier transform of an image, applying a filter ithe custency domain, and then performing an intverse Fourier transform to obtain the processed image. Common steps include:

  • Sampling the image to create a digitál represpatión.
  • Applying Fouriel transform algoritms like FFT (Fast Fourier Transform).
  • A "Diging filters such a s low-pass, high- pass, or band- pass in the custency domain".
  • Transporming back to to spatiad tz domain to visualize the result.

Design Strategies for Optical Systems

Effective design of optical systems using Fourier optics requirs consiging the system 's transfez function. Stratégia beleértve:

  • Optimizing apertura sizes to control spatienal spatiency bandwidth.
  • Usinglenses with consigate focol lengths to accesse desired Fourier transforms.
  • Végrehajtása digitál filters that mimic fizic el optical filters for real-time processing.
  • Ensuring system alignment to minimize aberrations s that torzítja Fourier Ingelents.
