1. An iris biometric recognition module comprising:

  • a base;

    an iris imager assembly supported by the base;

    a processor supported by the base and in electrical communication with the iris imager assembly; and

    a non-transitory storage medium supported by the base and readable by the processor, the non-transitory storage medium having embodied therein a plurality of instructions executable by the processor to cause the iris biometric recognition module to;

    with the iris imager assembly, capture an iris image, the iris image depicting at least a portion of an iris of an eye of a human subject detected in a capture zone;

    with the processor, compare data indicative of the captured iris image to reference iris data; and

    with the processor, based on the comparison of the data indicative of the captured iris image to the reference iris data, output a signal indicative of an iris match determination;

    wherein the iris imager assembly comprises an illuminator and an imager, and the instructions are executable to substantially synchronize pulsed illumination by the illuminator and iris image capture by the imager using a focal sweep technique.
