1. An apparatus for illuminating a target, the apparatus comprising:

  • a light guide having a non-circular cross-section to receive and guide a plurality of spatial modes excited by at least one beam of light, the light guide comprising;

    a first segment defining a first window to transmit a first spatial mode in the plurality of spatial modes into and out of the light guide; and

    a second segment in optical communication with the first segment, the second segment defining a second window to transmit a second spatial mode in the plurality of spatial modes into and out of the light guide; and

    a photodetector array, in optical communication with the light guide, comprising a first photodetector to sense light in the first spatial mode transmitted into the light guide via the first window and a second photodetector to sense light in the second spatial mode transmitted into the light guide via the second window.
