1. An apparatus for use in determining spin characteristics of a rotating object, said apparatus comprising:

  • a transmitter positionable for transmitting electromagnetic radiation of at least a first frequency at an object configured for reflecting at least a portion of said transmitted radiation in a modulated manner wherein said reflected radiation includes modulation characteristics from which at least a spin axis of the object is determinable;

    a receiver positionable for receiving at least a portion of said reflected radiation; and

    a demodulator for detecting the modulation characteristics of said reflected radiation received by said receiver and outputting a demodulated signal including information about at least the spin axis of the object.
