Single and multiple-nested conical mirrors assembled and positioned to provide several distinct orders of retroreflection. Design and orientation of "cones" determines positions of, and solid angles subtended by discrete orders of retroreflection. Accommodates larger range of incident angles than corner-cube reflectors. Also provides greater spectral coverage than conventional lens-and mirror retroreflectors. Potential applications include interferometry, metrology, lasers, position and motion sensors, instrument test and calibration, and expanded capability of highway markers and signs.
