First Claim
1. A measurement system, comprisinga source of radiation having one or more wavelengths capable of penetrating through an obstruction, said source being movably positioned on one side of the obstruction for illuminating thereof with said radiation,a reflecting imaging element adapted for placement at a measurement location of interest on another side of the obstruction, said reflecting element being capable of reflecting at least a portion of the radiation transmitted through the obstruction, anda plurality of radiation sensors positioned relative to the obstruction so as to detect at least a portion of the reflected radiation transmitted through the obstruction so as to determine a position of said source relative to said reflective elementwherein said reflecting imaging element is configured to retro-focus the radiation to form an image of the source.

Abstract
In one aspect, a measurement system is disclosed that includes a source of microwave radiation having one or more wavelengths capable of penetrating through a visibly opaque obstruction, e.g., a wall. The source can be movably positioned on one side of the obstruction for illuminating thereof. The system can further include a microwave reflecting element disposed on another side of the obstruction, where the reflecting element is capable of reflecting at least a portion of the radiation transmitted through the obstruction. A plurality of radiation sensors are positioned relative to the obstruction so as to differentially detect at least a portion of the reflected radiation transmitted through the obstruction so as to determine a position of the source relative to the reflective element.

12. A measurement method, comprising
movably disposing a radiation source on one side of a visibly opaque obstruction, said source generating radiation having at least one wavelength capable of penetrating through said obstruction, associating a reference imaging element to a location at an opposed side of said obstruction, said element being reflective to said at least one wavelength and being configured to retro-focus at least a portion of radiation incident thereon to form an image of said source, directing a radiation beam having said wavelength from the source to the obstruction such that at least a portion of said radiation penetrates the obstruction to illuminate said reference element, and detecting at least a portion of radiation reflected by said element at two or more spatially separate locations so as to determine a position of the source relative to the reflective element.
