Prof. Mack, i really appreciate for all the materials you posted on youtube. These are very education for me and all my coworkers in semiconductor industry.
Q1: When the imaging system has ideal lens, the only limitation comes from the diffraction Q2: spatial frequency (fx, fy) forms a transform cordinate of (x,y), which contains the information of diffraction angle theta. Q3: light propagates as a planner wave, each point can be regarded as a point light source and has its own propagating funtion, by adding up all the propagation functions, we can figure out the light distribution at any spatial position. Q4: With a specific mask pattern, we can figure out the mask transparent funciton tm(x,y), then do the fourier transform convert it to Tm(fx, fy), in which the fx,fy represent the componnet with different diffraction angles, and the amplitude represent the electric field amplitude of these component.
very nice lecture - you explain things very well - thank you! I was a semiconductor lithography/manager for 12 year and now teach technicians and run a NSF Center - the Southwest Center for Microsystems Education. I'm using your materials in my advanced fabrication/spc course. Wonderful stuff!

Wonderful lectures Sir! NOthing can be a better explanation than this!! Salute Sir!!

Excuse me. Question: Slide 10: The formular under "Equal lines and spaces", where the 1/p comes from?
