Abstract
Apparatus for optically measuring a remote object comprises at least one source for projecting a plurality of discrete zones of electromagnetic radiation (for example laser spots) along a projection plane. Imaging apparatus images a plurality of reflections from the remote object. By spatially offsetting the imaging apparatus from the projection plane, crosstalk between opposing cameras imaging the same object is more easily avoided. The same effect as spatially offsetting the imager can be achieved by rotating the light source to provide a reflection axis that is not perpendicular to the optical axis.
