IMAGING A POINT TO A LINE WITH A SINGLE SPHERICAL MIRROR

Methods for imaging a single point source to a line image are discusse d, and a design study of single spherical mirror systems that form abe rration-free line images is presented. An expression for the ray densi ty along the line image is derived for such systems in the cases of (i ) uniform beam profiles and (ii) Gaussian beam profiles. The resulting ray density profiles are illustrated for single spherical mirror syst ems over a wide range of design parameters. (C) 1998 Optical Society o f America.
