1. A target marking system, comprising:

  • (a) a light source configured to emit a thermal beam having a particular temporal modulation;

    (b) an optics assembly configured to direct the emitted beam to impact a target, and to receive radiation from the target in response to the impact, a portion of the radiation received from the target having the particular temporal modulation;

    (c) a detector configured to;

    receive the portion of the radiation via the optics assembly,detect the particular temporal modulation, andgenerate a corresponding output signal; and

    (d) a display operably connected to the detector, the display being configured to display an image based at least partly on the output signal, the image illustrating;

    at least part of the emitted beam,a point of impact of the emitted beam separate from the at least part of the emitted beam, anda portion of the target impacted by the emitted beam.
