Vehicle measurement system
A vehicle measurement system includes a laser projector which is designed to generate suitable laser radiation during the vehicle measurement operation, and a laser protection device which is suitable for protecting people and objects from the laser radiation. The laser projector and the laser protection device are designed as separate components and are combinable to form a laser projector having a laser protection device and are separable from one another again.
1. A vehicle measurement system, comprising:
a laser projector configured to generate laser radiation for vehicle measurement;
a laser protection device configured to protect persons and objects from the laser radiation generated by the laser projector; and
a laser beam sensor integrated into the laser projector;
wherein the laser projector and the laser protection device are separate components which are configured to be (i) selectively attached to one another to form an integrated system and (ii) subsequently detached again,
wherein the laser protection device has at least one mirror configured for deflecting at least one portion of the laser radiation generated by the laser projector, and
wherein the at least one mirror reflects at least one portion of the laser radiation generated by the laser projector onto the laser beam sensor when the laser protection device is attached to the laser projector.
2. The system as recited in claim 1 , wherein the laser projector is configured to be operable only when the laser projector is attached to the laser protection device.
3. The system as recited in claim 2 , wherein the laser projector includes:
a laser beam source;
a diffraction grating; and
one of a deflecting mirror or a deflecting prism positioned to deflect the laser beam generated by the laser beam source onto the diffraction grating.
4. The system as recited in claim 2 , wherein the laser protection device is configured to be mountable directly on the laser projector.
5. The system as recited in claim 2 , further comprising:
a support configured to be mechanically connected to the laser projector and at least one camera.
6. The system as recited in claim 5 , wherein one of (i) the laser protection device is configured to be mounted on the support, or (ii) at least a portion of the support forms the laser protection device.
7. The system as recited in claim 1 , wherein the at least one mirror has a nonreflective edge.
8. The system as recited in claim 1 , wherein the laser protection device has at least one beam trap configured to absorb at least a portion of the laser radiation generated by the laser projector.
