PRISMATIC CORNER REFLECTOR Russian patent published in 1998 - IPC

FIELD: orientation and location systems, interferometers, range finders and lidars. SUBSTANCE: prismatic corner reflector is manufactured in the form of trihedral pyramid which two dihedral angles between side reflecting faces are right angles and third angle is equal to π/[12(S+1)]. In agreement with invention sectors of working aperture in input frontal face of reflector corresponding to order of reflection of light from side faces in which face opposite to dihedral angle π/[2(S+1)] is not in middle of network of 2S+3 total internal reflections are screened. S=1, 2...7 and refractive index of material of reflector is chosen equal to n=1.73 for S=1; n=1.46 for S= 2; n=1.41 for S=3; n=2.41 for S=4; n=1.77 for S=5; n=159 for S=6; n=1.50 for S= 7. EFFECT: enhanced functional characteristics of proposed reflector. 4 dwg
