RETRO-REFLECTING ELEMENT USED FOR MODELLING REFLECTIVE PROPERTIES OF LIGHT, INCLUDING LASER RADIATION

摘要

FIELD: physics. ^ SUBSTANCE: invention can be used in optical-mechanical industry for manufacturing retro-reflecting elements of laser location systems. Retro-reflecting element represented with biconvex lens of curvature radiuses R1 and R2 made of optically transparent material of refraction indicator n, ensures element parametric association is specified providing conditions: R1/(n-1).0.8<=R2<=R1/(n-1).1.1, -0.11(R1+R2)<=delta<=+0.11(R1+R2), d=R1+R2±delta, where: R1 is curvature radius of the first element surface; R2 is curvature radius of the second element surface; delta is R2 decentration, d is a axial element thickness. ^ EFFECT: higher range of retro-reflecting element within wide interval of retro-reflecting angles. ^ 5 cl, 2 dwg
