Abstract:
Reflector contours called macrofocal parabolas are derived for use in aerial photography. These contours represent the most efficient reflector designs possible for a given aperture, field angle and finite sized light source. In addition, they give the smallest possible aperture which will reflect 100 of the emitted light into a given beam size. By reducing the efficiency, the reflector contours can be adjusted to tailor the radiant intensity distribution. Author
