Abstract

An elongate object optically determines at least one of its orientation parameters relative to a plane surface. A probe radiation beam is directed from the object at various angles σ to various locations on the plane, where the angle σ is a periodic function of time. Two angularly-selective radiation detectors oriented at fixed angles τand τsense scattered portions of the beam from two locations at two corresponding times. The orientation parameter is computed from a time difference Δt=t−tbetween the two times.
