International Workshop on Accelerator Alignment

Laser beam trajectory measurement with a CCD camera

Description

In some cases traditional autocollimation techniques cannot be used for surface alignment, either due to the surface not being reflective enough, or being curved, or the line-of-sight normal to the surface not being accessible. This paper provides examples on how we are using a laser and a CCD camera to map the location and orientation of various surfaces.
