Optical device for the determination of the spacing of an object and its angular deviation relative to an initial position
Abstract
Abstract A MULTI-PURPOSE OPTICAL MEASURING DEVICE IN WHICH AN IMAGE OF AN OXCILLATING LUMINOUS SCANNING MARK IS PROJECTED, VIA A BEAM SPLITTER AND AN OBJECTIVE LENS, ONTO A REFLECTING SURFACE OF AN OBJECT TO BE LOCATED, POSITIONED, OR MEASURED, OR ONTO A REFLECTOR RIGIDLY CONNECTED THERETO. THE IMAGE OF THE SCANNING MARK, AFTER REFLECTION FROM THE OBJECT, IS PROJECTED THROUGH THE OBJECTIVE LENS AND THE BEAM SPLITTER ONTO AN INDEX CARRIER HAVING A PLURALITY OF INDICES. SAID IMAGE COACTS WITH SAID INDICES TO PRODUCE OPTICAL SIGNALS WHICH ARE INDICATIVE OF ANY LATERAL OR ANGULAR DISPLACEMENT OF THE OBJECT. AN EYEPIECE AND/OR A PHOTOELECTRIC TRANSDUCER ARE POSITIONED ADJACENT TO THE INDEX CARRIER FOR EVALUATION OF SAID SIGNALS.
