10.6‐&mgr;m radiation from a pair of point sources at optical infinity has been mixed with collimated ruby‐laser radiation in Proustite. The sum‐frequency radiation at 6516 Å so produced was then focused with a camera lens to form a visible image of the infrared sources. With a pump‐laser beam divergence of 1.2 mrad the minimum resolvable angular separation of the infrared sources was 15 mrad according to the Rayleigh criterion.
