Abstract: Swept polarization optical beams are directed to a sample to produce fluorescence. typical as a plurality of single photon detection events. Based on frequencies associated with the polarization sweeps, orientation of a sample can be determined. Using polarization sweeps at first and second frequencies and wavelength, donor fluorophore orientation can be established based on the first frequency and wavelength and acceptor orientation can be established based on a sum or difference of the first and second frequencies and the second wavelength.

Abstract: A cut off conductive enclosure tube supports a plurality of wire-like energy coupling elements partially wrapped about a centrally located dielectric support tube for receiving a frankfurter or other material body. Each coupling element is excited by an independent low power source of microwave energy, the energy coupled to different regions of the body being absorbed thereby to provide isolation between coupling elements and sources. Continuous processing operations are possible, and a rectangular configuration and industrial heating applications are described.
