Method and means for enhancing camouflaged target detection utilizing light polarization techniques

Claim 2

IN A PASSIVE METHOD FOR DETECTING AND IDENTIFYING A TARGET DISPOSED IN A CLUTTERED BACKGROUND, THE STEPS OF: FILTERING SURFACE REFLECTED LIGHT RAYS THROUGH A POLARIZER FOR OBTAINING QUANTITIES OF IMAGE INTELLIGENCE; CONVERTING FILTERED SURFACE REFLECTED POLARIZED LIGHT RAYS TO QUANTITIES OF IMAGE INTELLIGENCE BEARING ELECTRONIC PULSES; CANCELING FROM SAID PULSES UNDESIRED INTELLIGENCE INTIATED THROUGH FILTERED NONPOLARIZED LIGHT EFFECTS; AND CONVERTING SAID PULSES TO AN ELECTRONIC VISUAL DISPLAY WHEREIN THE DESIRED INTELLIGENCE IS PRESENTED AS OPTIC FIELD IMAGES.

Claim 3

A TELEVISION SYSTEM FOR PROVIDING AN ELECTRONIC VISUAL DISPLAY OF AN OPTIC FIELD OF VIEW DISPOSED THEREIN SUBJECTS CAPABLE OF REFLECTING A BEAM OF LIGHT BOTH POLARIZED AND UNPOLARIZED LIGHT RAYS COMPONENTS COMPRISING IN COMBINATION: MEANS FOR DIRECTING SAID LIGHT BEAM ALONG A FIRST AND A SECOND LIGHT BEAM PATH; A POLARIZER DISPOSED IN SAID FIRST PATH FOR SELECTIVELY TRANSMITTING LIGHT RAYS HAVING A PREDETERMINED POLARIZATION ORIENTATION; MEANS FOR CONVERTING IMAGE INTELLIGENCE CONTAINED WITHIN SAID PRESELECTED LIGHT RAYS TO A FIRST SERIES OF VIDEO OUTPUT SIGNALS; MEANS FOR CONVERTING IMAGE INTELLIGENCE CONTAINED WITHIN SAID BEAM AS IT IS DIRECTED ALONG SAID SECOND PATH TO A SECOND SERIES OF VIDEO OUTPUT SIGNALS IRRESPECTIVE OF COMPONENT RAY POLARIZATION; A SIGNAL INVERTER FOR ESTABLISHING AN INVERTED PHASE RELATIONSHIP BETWEEN SAID FIRST AND SECOND SERIES OF VIDEO OUTPUT SIGNALS; MEANS FOR ELECTRONICALLY ADDING SAID SERIES OF VIDEO OUTPUT SIGNALS FOR PROVIDING A SERIES OF DIFFERENTIAL OUTOUT SIGNALS; AN ELECTRONIC DISPLAY DEVICE; AND MEANS FOR DRIVING SAID DISPLAY DEVICE IN ACCORDANCE WITH IMAGE INTELLIGENCE CONTAINED IN SAID SERIES OF DIFFERENTIAL SIGNALS TO PROVIDE AN ELECTRONIC IMAGE REPRODUCTION OF SAID OPTIC FIELD, WHEREIN SAID OPTIC FIELD SUBJECTS REFLECTING POLARIZED LIGHT RAYS HAVING A PREDETERMINED ORIENTATION ARE DISPLAYED IN SIGNIFICANT CONTRAST WITH RESPECT TO REMAINING SUBJECTS OF SAID OPTIC FIELD.

Claim 4

A TELEVISION SYSTEM FOR PROVIDING AN ELECTRONIC VISUAL DISPLAY OF AN OPTIC FIELD OF VIEW DISPOSED THEREIN SUBJECTS CAPABLE OF REFLECTING A BEAM OF LIGHT BOTH POLARIZED AND UNPOLARIZED LIGHT RAYS COMPONENTS COMPRISING IN COMBINATION: MEANS FOR DIRECTING SAID LIGHT BEAM ALONG A FIRST AND A SECOND LIGHT BEAM PATH; A POLARIZER DISPOSED IN SAID FIRST PATH FOR SELECTIVELY TRANSMITTING LIGHT RAYS HAVING A PREDETERMINED POLARIZATION ORIENTATION; MEANS FOR CONVERTING IMAGE INTELLIGENCE CONTAINED WITHIN SAID PRESELECTED LIGHT RAYS TO A FIRST SERIES OF VIDEO OUTPUT SIGNALS; MEANS FOR CONVERTING IMAGE INTELLIGENCE CONTAINED WITHIN SAID BEAM AS IT IS DIRECTED ALONG SAID SECOND PATH TO A SECOND SERIES OF VIDEO OUTPUT SIGNALS IRRESPECTIVE OF COMPONENT RAY POLARIZATION; A SIGNAL INVERTER FOR ESTABLISHING AN INVERTED PHASE RELATIONSHIP BETWEEN SAID FIRST AND SECOND SERIES OF VIDEO OUTPUT SIGNALS; MEANS FOR ELECTRONICALLY ADDING SAID SERIES OF VIDEO OUTPUT SIGNALS FOR PROVIDING A SERIES OF DIFFERENTIAL OUTOUT SIGNALS; AN ELECTRONIC DISPLAY DEVICE; AND MEANS FOR DRIVING SAID DISPLAY DEVICE IN ACCORDANCE WITH IMAGE INTELLIGENCE CONTAINED IN SAID SERIES OF DIFFERENTIAL SIGNALS TO PROVIDE AN ELECTRONIC IMAGE REPRODUCTION OF SAID OPTIC FIELD, WHEREIN SAID OPTIC FIELD SUBJECTS REFLECTING POLARIZED LIGHT RAYS HAVING A PREDETERMINED ORIENTATION ARE DISPLAYED IN SIGNIFICANT CONTRAST WITH RESPECT TO REMAINING SUBJECTS OF SAID OPTIC FIELD.
