Ders Kodu |
OPE560 |
Ders Açıklama |
Fundamentals of Image Formation: Diffraction theory of image formation with emphasis on aberrations, Compare diffraction and geometrical PSFs and OTFs, Strehl, Hopkins, and Struve ratios, Asymptotic behavior of PSF. Imaging by systems with circular pupils: Aberration-free PSF and beam focusing, Strehl ratio and aberration balancing and tolerance, Zernike circle polynomial expansion of aberration function, Aberrated PSF and its symmetry properties, Encircled and ensquared power, Aberrated OTF and Hopkins ratio, Line of sight and centroid of PSF of an aberrated system, Line-spread function and Struve ratio, Polychromatic PSFs and OTFs. Imaging by systems with annular pupils: Discuss similar topics as for systems with circular pupils, including Zernike annular polynomials. Imaging by systems with Gaussian pupils: Effect of Gaussian apodization on PSF and OTF, Zernike-Gauss polynomials and aberration balancing, Propagation of Gaussian beams. Random Aberrations: Random image motion, Fabrication errors, Propagation through atmospheric turbulence. |
