OPTICAL RANGING APPARATUS COMPRISING: (1) A SOURCE OF LIGHT; (2) MEANS HAVING AN AXIS EXTENDING IN THE DIRECTION OF RANGING FOR RECEIVING AND FOCUSING LIGHT REFLECTED FROM AN OBJECT WHOSE DISTANCE IS TO BE MEASURED; (3) MEANS FOR FORMING LIGHT FROM SAID SOURCE INTO A COLLIMATED LIGHT BEAM AND FOR PROJECTING SAID BEAM TOWARD SAID OBJECT, THE AXIS OF SAID COLLIMATED BEAM INTERSECTING THE AXIS OF SAID FOCUSING MEANS AT A DISTANCE, D, FROM THE PLANE OF SAID FOCUSING MEANS, THE AXIS OF SAID COLLIMATED BEAM ALSO INTERSECTING THE PLANE OF SAID FOCUSING MEANS AT A VERTICAL DISPLACEMENT, S, FROM THE AXIS OF SAID FORCUSING MEANS; (4) ROTATABLE MEANS FOR INTERSECTING THE FOCUSING LIGHT REFLECTED FROM SAID OBJECT, WHEREBY AN IMAGE SPOT IS FORMED ON SAID ROTATABLE MEANS BY THE REFLECTION OF SAID COLLIMATED BEAM, SAID ROTATABLE MEANS BEING MOUNTED AT A DISTANCE, L, FROM SAID FORCUSING MEANS MEASURED ALONG THE OPTICAL PROJECTION OF THE AXIS OF SAID FOCUSING MEANS AND PREPENDICULAR TO SAID OPTICAL PROJECTION, THE AXIS OF ROTATION OF SAID ROTATING MEANS BEING DISPLACED BY A DISTANCE, RO=SL/D, FROM THE OPTICAL PROJECTION OF THE AXIS OF SAID FOCUSING MEANS SUCH THAT THE ANGULAR DISPLACEMENT OF SAID IMAGE SPOT ON SAID ROTABLE MEANS IS A LINEAR FUNCTION OF THE DISTANCE OF SAID OBJECT FROM THE PLANE OF SAID FOCUSING MEANS; AND (5) MEANS FOR PERIODICALLY MEASURING SAID ANGULAR DISPLACEMENT IN TIMED RELATION TO SAID ROTATABLE MEANS AND FOR GENERATING AN ELECTRICAL SIGNAL REPRESENTATIVE THEREOF.
