Abstract
A compact optical assembly is disclosed for use in controlling the direction of radiation from a scene in a scene evaluating arrangement. Included in this assembly is an arrangement having different optical portions for optically directing scene radiation along independent paths to an array of closely spaced photoresponsive regions. At least a pair of adjacent optical portions directs the scene light along adjacent paths such that portions of scene light along the adjacent paths would intersect prior to reaching at least one region. Means for internally reflecting at least some of the scene radiation which would intersect is provided so as to reduce optical crosstalk between the adjacent paths.
