Embodiment Construction

[0052] The collimator housing 1 is shown in the figure. In the illustrated embodiment, the collimator housing 1 consists of four longitudinal walls, here a first 8 and a second 9 longitudinal wall are shown. 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 .

[0053] Here, the first end wall 10 includes the light source 2 and the second end wall 11 includes the lens 5 .

[0054] Furthermore, the two longitudinal walls 8 , 9 include, if desired, mirrors 13 arranged inside the collimator housing 1 to reflect the light beam emitted from the light source 2 . In the illustrated embodiment, a mirror 13 extends from the collimator housing 1 towards the camera 6 . In another embodiment, the mirrors are only on the longitudinal walls 8,9.

[0055] Furthermore, a diffuser 3 is arranged between the reticle 4 and the light source 2 in the collimator housing 1 . In the exemplary embodiment shown, the reticle 4...

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).

Description

technical field [0001] The invention relates to a collimator according to the preamble of claim 1 . Background technique [0002] Such collimators are known and are being used in various forms and designs. For example, German Patent Laid-open Publication No. DE102007003681A1 discloses a method and a device for analyzing optical devices. In this case, the lighting device generates a test beam, which is detected by the optical device and the position-resolving sensor device, whereby they are arranged in a mutual reference position. [0003] Reference is also made to German Patent Laid-open Publication No. DE 10 2004 056 723 A1 which discloses an arrangement for geometric calibration of positron sensor systems, in particular for digital cameras. The signal of the photosensitive sensor is recorded in the evaluation and control unit. [0004] German Patent Laid-open Publication No. DE102014209040A1 discloses a method for calibrating a measuring device, wherein a measuring sign...
