摘要： A backscatter transponder interrogator, comprising a transmitter, emitting an interrogation signal for interacting with a backscatter transponder within an interrogation field, a plurality of antennas, each having a different and complementary property, such that a backscatter response from a backscatter transponder is likely to be preferentially received by at least one of said at least two antennas, a receiver, selecting an output from a selected antenna, and demodulating the backscatter response to produce an information signal, and a digitally controlled oscillator, producing an output controlling said transmitter and employed by said receiver to demodulate the backscatter response. The interrogator may have a plurality of transmit antennas. The antennas may have respectively different polarization properties, e.g., horizontal and vertical polarization. The interrogator may implement null steered polarization cancellation to distinguish between backscatter transponders within the interrogation field.

摘要： A "passive interrogator label system" (PILS) comprises an interrogator for transmitting an interrogation signal, one or more "labels" or passive transponders which produce a reply signal containing coded information in response to the interrogation signal, and a receiver and decoder for receiving the reply signal and decoding the information contained in it. The frequency of the interrogation signal assumes a plurality of frequency values within a prescribed frequency range. The decoder includes a mixer (4 quadrant multiplexer) for mixing together the interrogation and reply signals (or signals derived therefrom) to produce a further signal containing frequencies which are the sum and difference of the interrogation and reply signals. A signal processor, responsive to this further signal produced by the mixer, detects at least some of the frequencies contained in this further signal and determines the informational code associted with the transponder.

摘要： A plurality of optic modulators implemented using segmented electrodes and nonparallel waveguide structures are cascaded using optical couplers to provide a linearization of the overall electro-optic transfer function. Each of the optical modulators which are coupled in cascade have an electrode structure which is divided into a plurality of relatively small segments. The segments are connected via bond wires and transmission lines on an adjoining microwave circuit board. Each of the optical modulators includes a pair of waveguides which are sloped so as to result in a nonparallel waveguide structure which reduces acoustic effects, e.g., ripple. By using a plurality of small segments to implement the electrode structure a high degree of sensitivity is achieved as compared to when a single lengthy electrode structure is used. The combination of the non-parallel waveguides and a segmented electrode provides for a relatively large flat frequency response, e.g., in excess of 1 GHz. The electrode structure is also designed to minimize the effective capacitance of the electrode structure to thereby broaden the bandwidth of the optic modulator of the present invention as compared to devices using solid center electrodes.
