Abstract: | A new displacement measurement system is described in this paper according to the basic principles of traditional laser triangulation
method. The range of the traditional measuring method is enlarged by measuring in sections. Three independent CCDs, which
are distributed uniformly along the optical axis, are used to achieve subsection measurement. The plane mirror is regarded
as a virtual detector. When imaging beam is reflected by the plane mirror, the beam is imaged on the CCD. The designed system
is equivalent to add a CCD. The feasibility of the displacement measurement system is verified by the experiment. |
