Optical search system

Claim 1

A SYSTEM FOR OPTICALLY SEARCHING THROUGH A FIELD OF VIEW DEFINED BY A FIRST PREDETERMINED ANGLE IN AN AZIMUTH PLANE AND A SECOND PREDETERMINED ANGLE IN A VERTICAL PLANE COMPRISING: A FLAT MIRROR; MEANS FOR CONTINUOUSLY ROTATING SAID MIRROR ABOUT ONE AXIS PERPENDICULAR WITH RESPECT TO SAID AZIMUTH PLANE; MEANS FOR SIMULTANEOUSLY IMPARTING A LIMITED NODDING MOTION TO SAID MIRROR THROUGH SAID SECOND ANGLE ABOUT A SECOND AXIS AT RIGHT ANGLES TO SAID ONE AXIS AND TO SAID VERTICAL PLANE; RADIATION DETECTION MEANS FOR RECEIVING RADIATION REFLECTED FROM SAID MIRROR AND FOR PROVIDING A SIGNAL RESPONSIVE THERETO, SAID RADIATION DETECTION MEANS BEING STATIONARY WITH RESPECT TO SAID AZIMUTH AND VERTICAL PLANES; A CATHODE RAY OSCILLOSCOPE HAVING ELECTRON BEAM PRODUCING MEANS AND VERTICAL AND HORIZONTAL BEAM DEFLECTION MEANS, MEANS COUPLING SAID ELECTRON BEAM PRODUCING MEANS TO SAID DETECTION MEANS FOR VARYING THE INTENSITY OF SAID ELECTRON BEAM RESPONSIVE TO SAID SIGNAL; MEANS COUPLING SAID NODDING MOTION IMPARTING MEANS AND SAID VERTICAL DEFLECTION MEANS FOR PROVIDING VERTICAL DEFLECTION OF SAID ELECTRON BEAM DIRECTLY RELATED TO SAID NODDING MOTION OF SAID MIRROR; HORIZONTAL SWEEP VOLTAGE GENERATOR MEANS COUPLED TO SAID HORIZONTAL DEFLECTION MEANS FOR PROVIDING HORIZONTAL SWEEP OF SAID ELECTRON BEAM; MEANS OPERATIVELY ASSOCIATED WITH SAID MIRROR ROTATING MEANS FOR PROVIDING SIGNALS RESPECTIVELY COINCIDENT WITH TWO SPACED ROTATIONAL POSITIONS OF SAID MIRROR DEFINING SAID FIRST ANGLE THEREBETWEEN; AND MEANS COUPLING SAID LAST NAMED MEANS TO SAID HORIZONTAL SWEEP VOLTAGE GENERATOR MEANS FOR RESPECTIVELY INITIATING AND TERMINATING SAID HORIZONTAL SWEEP RESPONSIVE TO SAID LAST NAMED SIGNALS.

Claim 2

A SYSTEM FOR OPTICALLY SEARCHING THROUGH A FIELD OF VIEW DEFINED BY A FIRST PREDETERMINED ANGLE IN AN AZIMUTH PLANE AND A SECOND PREDETERMINED ANGLE IN A VERTICAL PLANE COMPRISING: A FLAT MIRROR; MEANS FOR CONTINUOUSLY ROTATING SAID MIRROR ABOUT ONE AXIS PERPENDICULAR WITH RESPECT TO SAID AZIMUTH PLANE; MEANS FOR SIMULTANEOUSLY IMPARTING A LIMITED NODDING MOTION TO SAID MIRROR THROUGH SAID SECOND ANGLE ABOUT A SECOND AXIS AT RIGHT ANGLES TO SAID ONE AXIS AND TO SAID VERTICAL PLANE; RADIATION DETECTION MEANS FOR RECEIVING RADIATION REFLECTED FROM SAID MIRROR AND FOR PROVIDING A SIGNAL RESPONSIVE THERETO, SAID RADIATION DETECTION MEANS BEING STATIONARY WITH RESPECT TO SAID AZIMUTH AND VERTICAL PLANES; A CATHODE RAY OSCILLOSCOPE HAVING ELECTRON BEAM PRODUCING MEANS AND VERTICAL AND HORIZONTAL BEAM DEFLECTION MEANS, MEANS COUPLING SAID ELECTRON BEAM PRODUCING MEANS TO SAID DETECTION MEANS FOR VARYING THE INTENSITY OF SAID ELECTRON BEAM RESPONSIVE TO SAID SIGNAL; MEANS COUPLING SAID NODDING MOTION IMPARTING MEANS AND SAID VERTICAL DEFLECTION MEANS FOR PROVIDING VERTICAL DEFLECTION OF SAID ELECTRON BEAM DIRECTLY RELATED TO SAID NODDING MOTION OF SAID MIRROR; HORIZONTAL SWEEP VOLTAGE GENERATOR MEANS COUPLED TO SAID HORIZONTAL DEFLECTION MEANS FOR PROVIDING HORIZONTAL SWEEP OF SAID ELECTRON BEAM; MEANS OPERATIVELY ASSOCIATED WITH SAID MIRROR ROTATING MEANS FOR PROVIDING SIGNALS RESPECTIVELY COINCIDENT WITH TWO SPACED ROTATIONAL POSITIONS OF SAID MIRROR DEFINING SAID FIRST ANGLE THEREBETWEEN; AND MEANS COUPLING SAID LAST NAMED MEANS TO SAID HORIZONTAL SWEEP VOLTAGE GENERATOR MEANS FOR RESPECTIVELY INITIATING AND TERMINATING SAID HORIZONTAL SWEEP RESPONSIVE TO SAID LAST NAMED SIGNALS.
