Method of distance measurement using triangulation principle
摘要
the method involves directing light with components with distinguishable characteristics from at least two sources (5-8) coaxially towards the object. Each component is focussed at a different point on the line to produce a different light spot dia. Images of the spots are formed on a single detector which generates corresp. signals with distinguishable characteristics which are separately detected and identified to determine the distance
