I discussed the idea of two channel configuration fiber-optic-based (critical trait: no additional rad. emissions) system with Dr. Parviz Parhami of Cassper Div. of SARA, Inc. I learned later that SARA has filed for a patent (it is patent pending). The original system was developed for some DoD applications. It is inexpensive and rather elegant solution considering availability of hardware from SARA. One of two antennas sould be positioned at, say, 10m (or 30m, as required) from an EUT and the second antenna is placed at the predetermined distance from the first, such that the emissions from the EUT would be relatively negligible. The rest, differential data processing, is obvious. There are some metrological issues to be resolved.
For details, contact Dr. Parviz Parhami, e-mail: pparh...@sara.com.
