Diffraction, Fourier Optics and Imaging


Credit Hours:


Learning Objective:

i) Knowledge of important technologies based on wave propagation such as digital diffractive imaging techniques and devices involving principles of diffraction, Fourier analysis and synthesis techniques.
(ii) Knowledge of developments in areas of device fabrication and computer technology for fabrication of optical components and implementation of imaging/focusing modalities recently made possible.
(iii) Ability to deal with analysis of imaging and focusing techniques involving diffraction.
(iv) Knowledge of other topics, such as dense wavelength division multiplexing (DWDM) systems and devices, micro/nano systems in need of rigorous diffraction theory, image and phase recovery involving Fourier analysis and Fourier iterative optimization techniques, focusing of wave energy and daylighting.
(v) Ability to utilize theoretical analysis of topics based on Fourier analysis and synthesis for system and device fabrications.


Diffraction, Fourier Optics and Imaging covers topics central in diffractive optics, multidimensional Fourier methods and most modern analog and digital imaging/image processing techniques. Some algorithms discussed such as information recovery have close connections to other areas such as modern cryptography, super-resolution, lensless imaging, and modern printing/display technologies.
