Method and apparatus for measuring electromagnetic energy with photosensitive reflectors

Claim 1

IN APPARATUS FOR MEASURING RADIATED RADIO FREQUENCY ENERGY BY SENSING REFLECTIONS OF SAID ENERGY, THE COMBINATION OF (A) A REMOTELY CONTROLLABLE REFLECTOR FOR PRODUCING SAID REFLECTIONS, SAID REFLECTOR COMPRISING (1) PHOTOSENSITIVE MEANS HAVING AN ELECTRICAL IMPEDANCE THAT VARIES ACCORDING TO THE INTENSITY OF OPTICAL ENRGY INCIDNET THEREON, AND (2) ANTENNA MEANS IN CIRCUIT WITH SAID IMPEDANCE OF SAID PHOTOSENSITIVE MEANS, (B) MEANS DIRECTING AMPLITUDE MODULATED OPTICAL ENERGY ONTO SAID PHOTOSENSITIVE MEANS, AND (C) DIELECTRIC MEANS SUPPORING SAID ANTENNA MEANS AT A SELECTED POSITION RELATIVE TO THE SOURCE OF SAID RADIO FREQUENCY ENRGY.

Claim 2

A METHOD FOR MEASURING RADIO FREQUENCY ELECTROMAGNETIC ENRGY COMPRISING THE STEPS OF (A) INTERCEPTING SAIS ENERGY WITH A REMOTELY CONTROLLABLE PHOTOSENSITIVE REFLECTOR OF RADIO FREQUENCY ENERGY, (B) ILLUMINATING SAID REFLECTOR WITH INTENSITY MODULATED LIGHT, (C) MODULATING THE RADIO FREQUENCY IMPEDANCE OF SAID REFLECTOR IN ACCORDANCE WITH THE MODULATION OF SAID LIGHT, WHEREBY SAID REFLECTOR RERADIATES RADIO FREQUENCY ENERGY RESPONSIVE TO SAID INTERCEPTED ENERGY AND AMPLITUDE-MODULATED ACCORDING TO THE MODULATION OF SAID LIGHT, AND (D) PRODUCING AN OUTPUT INDICATION CORRESPONDING TO THE AMPLITUDE OF SAID RERADIATED ENERGY.
