Q1. One reasonable design goal for an imaging system is to match the air disk diameter to the detector size. That insures that a significant fraction of energy in the PSF is collected by the detector. If operational constrains specify that the detector is 15 Um square and the optical focal length is 12 m, what is the required optical aperture diameter at a blue wavelength? At red wavelength. At an NIR wavelength? If one optical system is to meet the design goal at all three wavelengths. What aperture diameter must be used?
Q2. A pitcher throws a fastball horizontally at a speed of 150 km/h toward home plate, 18.4m away. If the batters combined reaction and swing times total 0.37s, how long can batter watch the ball after it has left the pitcher's hand before swinging? In travelling to the plate, how far does the ball drop from its unique horizontal line?
