A target marking system includes a light source emitting a thermal beam having a predetermined temporal modulation, and an optics assembly directing the thermal beam to impact a target, the target directing radiation to the optics assembly in response to the impact. A portion of the radiation having the predetermined temporal modulation. The target marking system further includes a detector configured to distinguish the portion of the radiation having the predetermined temporal modulation from a remainder of the radiation, the portion of the radiation passing to the director through the optics assembly. The system also includes a readout integrated circuit, the detector directing an input signal to the readout integrated circuit, and the readout integrated circuit producing a digitally enhanced output signal in response to receipt of the input signal.
