Claim 1
Independent Claim

METHOD FOR DETERMINING THE VELOCITY OF A MOVING OBJECT, COMPRISING THE FOLLOWING STEPS; DIRECTING A FIRST SOURCE OF MONOCHROMATIC LIGHT OF CONSTANT FREQUENCY TOWARD THE OBJECT, THE VELOCITY OF WHICH IS TO BE DETERMINED; COMBINING THE BEAMS OF MONOCHRMATIC LIGHT FROM SAID FIRST SOURCE, REFLECTED BY SAID OBJECT, WITH A SECOND REFERENCE SOURCE OF MONOCHROMATIC LIGHT OF VARYING FREQUENCY; EXPOSING SAID COMBINED BEAMS TO THE SURFACE OF A PHOTO-SENSITIVE RECEPTOR; AND READING THE RESULTANT IMAGES TO DETERMINE THE CLEAREST IMAGE PRODUCED AS A RESULT OF THE SYNCHRONIZATION OF THE FREQUENCIES OF THE REFERENCE SOURCE AND THE REFLECTED LIGHT, THUS, TO DETERMINE THE RELATIVE RADIAL VELOCITY OF SAID OBJECT TO SAID FIRST SOURCE.
