Open the CIPO recordAbstract From the Canadian patent
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.
