Abstract
A system for measuring a lineal dimension of a light reflective object. Sequentially generated light markers forming a raster are projected toward the object to be measured, with the markers traveling along individual, parallel paths which are uniformly spaced-apart along the dimension being measured. Markers intercepted and reflected back by the object are photoelectrically detected and counted to determine the size of the object along the measured dimension.
