Abstract

The invention relates to an optical measuring apparatus ( 1 ) for a vehicle ( 6 ), having at least one optical transmitter, at least one optical receiver ( 12 ) and a deflection mirror arrangement having at least one deflection mirror ( 11 ), wherein the edge contour ( 27, 28 ) of a deflection mirror ( 11 ) of a reception unit of the measuring apparatus ( 1 ) matches the contour ( 41 ) formed by marginal rays ( 40 ) in a received beam ( 38 ). The invention also relates to a vehicle having such an apparatus ( 1 ).

First claim

The invention claimed is:

1. An optical measuring apparatus for a vehicle, comprising:
at least one optical transmitter;
at least one optical receiver; and
a deflection mirror arrangement having at least one deflection mirror,
wherein the deflection mirror has at least two opposite edge sides that do not run parallel to one another, and
wherein the deflection mirror has a trapezoidal shape which corresponds to a trapezoidal contour of marginal rays of a received beam, in a manner in which the marginal rays impinge on the deflection mirror.

2. The optical measuring apparatus according to claim 1 , wherein the deflection mirror is planar.

3. The optical measuring apparatus according to claim 1 , wherein a received beam path upstream of the deflection mirror contains a reception lens that has produced the contour of the marginal rays that is produced after the reception lens is penetrated.

4. A driver assistance device having an optical measuring apparatus according to claim 1 .

5. A vehicle having an optical measuring apparatus according to claim 1 , wherein the measuring apparatus is designed to sense objects in the vehicle surroundings, and the optical measuring apparatus has at least subcomponents arranged at a front region of a radiator grille on the vehicle.

6. The optical measuring apparatus according to claim 3 , wherein the deflection mirror is arranged obliquely with respect to the reception lens, with its tapered end further apart from a rear face of the reception lens than its opposite wider end.

7. The optical measuring apparatus according to claim 1 , wherein the measuring apparatus has a support on which a first alignment apparatus is formed that can set the position of a reception lens of the measuring apparatus, which reception lens is arranged in the received ray path, relative to the support and/or a second alignment apparatus is formed that can set the position of the deflection mirror, which is arranged in the received ray path, relative to the support.

8. The optical measuring apparatus according to claim 7 , wherein the reception lens has a retaining frame on which engagement elements for engaging in the first alignment apparatus are formed, in particular the retaining frame at least partially encompasses the perimeter of the reception lens.

9. The optical measuring apparatus according to claim 7 , wherein a first engagement element is arranged on a lower edge of the retaining frame and is in the form of a strip-like bracket.

10. The optical measuring apparatus according to claim 8 , wherein a first slot-like depression in the first alignment apparatus is formed in a base of the support and a first engagement element is arranged in the first depression so as to be rectilinearly displaceable in a first spatial direction and/or in a second spatial direction, which is perpendicular thereto, prior to the fixing of the position of the reception lens in relation to the support.

11. The optical measuring apparatus according to claim 8 , wherein a second slot-like depression in the first alignment apparatus is formed in a lateral wall of the support and a second engagement element is arranged in the second depression so as to be rectilinearly displaceable in a first spatial direction and/or in a second spatial direction, which is perpendicular thereto, prior to the fixing of the position of the reception lens in relation to the support.

12. The optical measuring apparatus according to claim 7 , wherein the second alignment apparatus has a first slot-like depression, which is accessible from above, in a support web of the support, into which depression a first retaining leg, which is connected to an upper edge side of the deflection mirror, is introduced, wherein the first retaining leg is rectilinearly displaceable relative to the support web in the second spatial direction prior to the fixing of the position of the deflection mirror in relation to the support, and/or the second alignment apparatus has a second slot-like depression in a base of the support, into which depression a second retaining leg, which is connected to a lower edge side of the deflection mirror, is introduced, wherein the second retaining leg is rectilinearly displaceable relative to the support in the second spatial direction prior to the fixing of the position of the deflection mirror in relation to the support.

13. The optical measuring apparatus according to claim 7 , wherein the relative positions, set using the alignment apparatuses, of the reception lens in relation to the support and of the deflection mirror in relation to the support are fixed by adhesive bonds.
