Abstract:
1. A sensor array, comprising: a plurality of sensors electrically connected in series or in parallel, each of the plurality of sensors operable to generate an individual electrical signal; a multiplexing scheme generator operable to generate a multiplexing scheme; a modulation system connected to the multiplexing scheme generator and operable to selectively reverse the polarity of each of the plurality of sensors for each of a plurality of samples based on the multiplexing scheme; a readout device operable to sequentially read a plurality of output signals of the plurality of electrically connected sensors, wherein the number of samples read is greater than or equal to the number of sensors and wherein one or more electrical signals of the plurality of sensors are readout as one electrical signal; and a demultiplexer operable to receive the output electrical signals and to determine the individual electrical signals of each of the plurality of sensors based on the multiplexing scheme.
