course covers the fundamentals of Fourier optics, including 2D Fourier
analysis, scalar diffraction theory, Fresnel and Fraunhofer diffraction theory,
lens model, and frequency analysis of optical systems. Part 3 of the course
covers digital image sensors, including CMOS pixels, photon shot noise, dark
current, pixel non-uniformity, conversion gain, analog-to-digital conversion.
