8. (10 points) Below is a schematic for a one-dimensional laser scanning microscope. The beam bounces off a mirror at A1 with diameter d1, and passes through a scan lens, is focused onto plane F1, and is recollimated by a longer lens that directs the beam onto the back aperture of the objective at plane Ac. a. (4 points) How are d1, 61, (19,60, the half angle of the beam focus (91:), and the eld of view (Fo) of the microscope related? b. (3 points) Is anything conserved? If so, what is conserved? c. (3 points) What are two types of distortion that can occur at plane F1
