DEVICE FOR CONTROLLING LASER RANGE-FINDER Russian patent published in 2015 - IPC G01M11/02 G01C3/08 

FIELD: physics.

SUBSTANCE: apparatus comprises input collecting and output collimating optical systems connected to each other by a fibre-optic delay line in the form of a light guide. The input and output ends of the light guide are located in the focal planes of the input and output optical systems, respectively. The input collecting and output collimating optical systems are formed by two coaxial menisci, whose concave side faces the end of the light guide and have a mirror coating on the convex surfaces. The mirror coating of the meniscus lying first from the end of the light guide is in the form of a peripheral annular area. At least one end of the light guide can be mated with a plane-parallel plate in an opaque area, having a diaphragm which is coaxial with the light guide, said diaphragm having a diameter smaller than the diameter of the light guide. At least one of the menisci can be glued.

EFFECT: producing a compact device with high manufacturability, high quality of forming laser beams and a simple design.
