<p>ELECTRO-OPTICAL DISTANCE-MEASURING SYSTEM Electro-optical apparatus for locating the surface of an object. A laser projects a beam along one axis. Light from the beam which is reflected by an impinged object is viewed along another axis, and is transmitted to a linear (straight-line) photodetector array. The array is specially oriented angularly relative to the viewing axis and to the laser beam axis, whereby, within the selected dynamic range of the apparatus, reflected light transmitted to the array is, under all circumstances, in sharp focus along the plane of the array.</p> |
