PRISMATIC CORNER REFLECTOR Russian patent published in 1998 - IPC

FIELD: location, indication of objects and obtainment of information on parameters of their movement. SUBSTANCE: proposed prismatic corner reflector is made in the form of thrihedral pyramid which dihedral angles between reflecting faces are equal to π/2, π/2, π/4. Frontal face of reflector limits lengths of its side ribs in relation R₁:R₂R₃=a:a:1, where value a related to ribs of right dihedral angles is found via refractive index n of material by means of mathematical expressions. EFFECT: enhanced accuracy and authenticity of obtained information. 3 dwg
