Abstract (en)

[origin: WO9957515A1] A laser beam (14, 32) is projected on to a plurality of aligned screens (11, 30a-d), each of which is partially opaque. The position at which the laser beam impinges on each screen is determined and measurement calculations carried out form the information thereby obtained.
