The photograph of a map is to be stored in microfilm, by using a lens with an aperture stop F#/1.2 and the focal length f= 100 mm. The highest spatial frequency on the map is 1 line/mm. Derive the maximum possible reduction ratio using this hardware. The wavelength of the illuminating light is a = 0.550 um, and the camera is assumed to be diffraction limited. Can you suggest ways of improving the resolution in the reduced image?
