This study introduces a novel two-step method combining ray tracing and diffraction theory to accurately compute the point-spread function for optical systems, enhancing image quality analysis.

Area of Science:

  • Optics and Photonics
  • Computational Electromagnetics

Background:

  • Accurate computation of the diffraction point-spread function (PSF) is crucial for optical system design and analysis.
  • Existing methods may rely on approximations that limit their applicability to general optical systems.

Purpose of the Study:

  • To present an accurate and versatile technique for computing the diffraction point-spread function (PSF) of optical systems.
  • To provide a method that is not limited by small-angle approximations and can handle general pupil shapes.

Main Methods:

  • A two-step computational procedure combining ray tracing and diffraction theory.
  • Ray tracing is used to determine wave-front errors and vignetted pupil shape.
  • Rayleigh-Sommerfeld diffraction, Kirchhoff approximation, and Stamnes-Spjelkavik-Pedersen numerical integration are applied to compute the image field.
