1. A particle detecting system comprising:

  • a first flow path having a detection region adapted to facilitate analysis or processing of a sample having one or more particles flowing through the first flow path of the detection region;

    a first optically detectable pattern associated with the detection region, the first optically detectable pattern positioned to receive a particle optical signal associated with a particle flowing through the first flow path of the detection region and to produce a patterned optical signal; and

    a first detector positioned to receive the patterned optical signal,wherein the first detector is configured to analyze the patterned optical signal to independently determine both;

    (i) a particle characteristic based on a property of the particle optical signal associated with the particle flowing through the detection region; and

    (ii) a particle parameter based on a property of the first optically detectable pattern.
