Abstract

1343196 Reflex reflectors L EIGENMANN 19 April 1971 [22 April 1970] 27194/71 Heading G2J A reflex reflector arrangement comprises a transparent sphere 20, having a part-spherical dome portion exposed and positioned for impingement of light, and a multiplicity of means, arranged about the spherical surface of the core sphere 20, said means including an at least part spherical reflecting element with a radius not greater than one fifth of the radius of the core sphere, the means focusing a beam refracted by the core sphere and reflecting the beam into the core sphere along a path essentially coincident with that of impingement. The means may be spheres 22 Fig.7, the reflective coatings of spheres 122 Fig.9 or merely curved reflecting areas Figs. 10 and 11 (not shown).
