发明名称 Transducer-based sensor system with multiple drive signal variants
摘要 A sensor system including a plurality of transducer groups, with each transducer group having a plurality of transducers. The transducers of each group are adapted to be placed in operative proximity with a sample material. Within each transducer group, each transducer is actuable via application of a different phase-shifted variant of a local oscillator signal to the transducer. The sensor system is also configured so that, for each transducer group, the phase-shifted variants of the local oscillator signal are selectively employed during output processing to inhibit cross-transducer interference occurring between simultaneously active transducers.
