1. A system for determining the orientation of an object relative to a source of electromagnetic radiation comprising:

  • a two-dimensional array of sensors, each of the sensors producing a corresponding output signal when placed in the path of electromagnetic radiation emitted by the source;

    a radiation director that directs the electromagnetic radiation from the source onto the two-dimensional array of sensors; and

    a controller that receives the output signals of the sensors, and that determines the orientation of the object relative to the source based on the output signals of the sensors.
