COLLIMATOR

Abstract

The invention relates to a collimator for testing a camera (6), comprising a collimator housing (1), wherein the collimator housing (1) has a longitudinal wall (8, 9) and two end walls (10, 11), the first end wall (10) having a light source (2) and the second end wall (11) having a lens (5), a reticle (4) being disposed between the lens (5) and the light source, with the reticle (4) being disposed obliquely with respect to the lens (5) and/or obliquely with respect to the longitudinal wall (8, 9) in the collimator housing (1).

Claims

1. Collimator for testing a camera (6) with a collimator housing (1), wherein the collimator housing (1) has a longitudinal wall (8, 9) and two end walls (10, 11), wherein the first end wall (10) has a light source (2) and the second end wall (11) has a lens (5), wherein a reticle (4) is arranged between the lens (5) and the light source (2), wherein the reticle (4) is arranged in the collimator housing (1) obliquely to the lens (5) and/or obliquely to the longitudinal wall (8, 9).

2. Collimator according to claim 1, wherein a diffuser (3) is arranged between the reticle (4) and the light source (2).

3. Collimator according to claim 1, wherein the longitudinal wall (8, 9) has a mirroring (13).

4. Collimator according to claim 1, wherein the camera (6) is connected to a computer (12).

5. Collimator according to claim 1, wherein the camera (6) is adjustable.

6. Method for testing a camera (6) with a collimator according to claim 1, comprising the following steps: the light source (2) illuminates the obliquely arranged reticle (4); the camera (6) captures an image generated by the reticle (4) through the lens (5); the camera (6) is shifted towards or away from the lens (5), whereby the computer (12) thereby performs an ACTUAL/NOMINAL comparison.

7. method according to claim 6, wherein the light source (2) shines through the diffuser (3).

Description

BRIEF DESCRIPTION OF THE FIGURES

[0045] Further advantages, features and details of the invention result from the following description of preferred embodiment and from the drawing; this shows in the FIGURE a schematic sectional drawing of the collimator according to the invention.

DETAILED DESCRIPTION

[0046] A collimator housing 1 is shown in the FIGURE. In the embodiment shown, the collimator housing 1 consists of four longitudinal walls, the first longitudinal wall 8 and the second longitudinal wall 9 being shown here. The two longitudinal walls 8, 9 are connected at one end by a first end wall 10 and at the other end by a second end wall 11.

[0047] Here, the first end wall 10 comprises a light source 2. The second end wall 11 comprises a lens 5.

[0048] In addition, the two longitudinal walls 8, 9 comprise a mirroring 13, the mirroring 13 being provided on the inner side of the collimator housing 1 to mirror light beams emitting from the light source 2, if necessary. In the embodiment shown, the mirroring 13 extends out of the collimator housing 1 towards the camera 6. In another embodiment, the mirroring is exclusively on the longitudinal walls 8, 9.

[0049] Furthermore, a diffuser 3 is arranged in the collimator housing 1 between a reticle 4 and the light source 2. The reticle 4 is arranged obliquely to the lens 5 in the embodiment shown. It is also arranged obliquely to the second end wall 11 or to one of the longitudinal walls 8, 9.

[0050] Further, a shift direction 7 indicates how a camera 6 can be shifted toward the lens 5 or shifted away from the lens 5. It is further shown that the camera 6 is connected to a computer 12. Here, the computer 12 is designed in such a way that the images taken by the camera 6 are recorded in an ACTUAL/NOMINAL comparison and compared with the data stored by the reticle 4.

[0051] In doing so, the camera 6 can be moved towards or away from the lens 5 by a device not shown in more detail.
