The invention relates to cjnTiiuec instrumentation and location technology and can be used as a retroreflective element in the control of dvigseni and the position of objects in transport, aviation, meteorology.

This goal is caused by the fact that there are three mirror-reflecting faces about the corner angle of the fir tree,

forming a triangular angle. The total dihedral angles of which are made straight, complementary to three flat bilateral mirrored reflecting elements installed at the place of the bisector planes of the reflector dihedral angles.

Additional flat two-sided mirror-reflecting elements, together with faces of a carbon corner reflector, form new types of reflectors that are independent of one another, which do not violate the properties of the return angle, and the spatial angle corresponding to the right angle reflector.

This allows to increase the rigidity of the structure of the corner branch, of the body and to implement a new mechanism for forming a return reflection, which increases the reliability of work.

Faces 1–3, hatched in FIG. 1, are angled reflector, the image is triangular angle i. The angled angles between facets 1 and 2, 2 and 3, 3 and 1 are 90. Flat two-sided mirror-reflecting electr :: chty 5 7 divides trihedral angle A into six trihedral corners, from which the corner angles are 90 °, 60 ° and t5 °. In this case, the elements 5-7 are located at the place of the bisector planes of the straight dihedral yi lines and separate each of the corners, at the faces 1 and. , 1 and 3, 2 and 3 for two pwuhl ula on) 5 and Pereis-, klptts among themselves, form six pnugranny corners in 60.

The reflector works as follows about

A beam of rays falls on the reflector and, having reflected from its faces, always comes out of the reflector in the direction, colline-ern, the ORIGINAL.

The beam entering the reflector, in accordance with the laws of geometrical optics, is distributed in it depending on the exoqa point not determined from 2 possible methods of reflection, in each of which it experiences a 9-fold reflection from its faces. All 2 methods of rereflection can be formally obtained from the following six variants of the incident beam propagation by cyclic permutation of the faces included in them:

where the arrow indicates the succession of the reflection from the edges 8-10. The image space, formed in the If / 2 reflector, fT / 3, f /, is oriented mirror-symmetrically to the vertical space relative to the vertex of the reflector. This causes the.-Ifo range of the angles of the return reflection of the reflector pl and / 2, H / 3, fr / i to lie in the spatial angle multiplier and / 12 steradians corresponding to this reflector. The cutting of a reflector into six reflectors, 1T / 3, / |: / according to the invention is carried out in such a way that these reflectors completely and without gaps fill the projection angle 1G / 2 steradians (6 and / 12 1G / 2) . Consequently, the return mirror reflection in the range of the space angle / 2 is not divided by the introduction of additional flat two-sided mirror-reflecting elements. At the same time, the division from the ra- i ate into separate reflections of the cell at the same time leads to an increase in the working time of the proposed corner reflector. For example, when leaving a single face, say, face 1, the property of return reflection is retained for three components of the parameters C Grazh 1tep- - 1 fT / 2,, for WHICH the floor; | not ppp ps obyuyutsy (fig, 1), the well-known reflector property nr.L p jTHoro reflection is completely tread. The refill elements 5-7, in addition, are stiffeners that increase the mechanical strength of the structure. In general, the probability of failure of the proposed reflector here is significantly lower than that of a direct reflector.

Thus, the proposed reflector provides high reliability of operation, longer service life, which increases the efficiency of the location of location systems.

The corner corner reflector contains three specularly reflecting faces that form a triangular angle, all of which are dihedral angles that are straight, so that, in order to increase the rigidity of the structure and reliability her work, in addition to the reflector, three flat two-sided mirror-reflecting elements, installed at the place of the bisector planes of the reflector angles, were added. 6
