Consider the 4-f system below where an object is placed at the input plane and is illuminated by a plane wave
With the object from part a) inserted in the input plane, a mask (shown to the right) is placed at the mask plane. The diameter of the hole is 10 µm. Again black blocks light and white passes light. Sketch what appears at the output plane and describe it in words. Again label as needed.
Sketch the x-y intensity pattern that appears at the mask plane. Label your sketch with as much detail as possible (distances to features, dimensions of features, axes, etc.) to get maximum marks. A sketch without any labels will receive minimal (probably zero) marks.
