Comparison of Lens Response for Sinusoidal and Square-Wave Targets at Several Focal Positions
A study has been made of the sine-wave and square-wave responses of a lens at two apertures and several focal positions, both on- and off-axis. Two focal positions, one of which gives the best definition and the other the highest contrast for coarse patterns, were located precisely. At these focal p...
