Encoded signal detection and display
First Claim
1. A target marking system, comprising:
- (a) a light source emitting a divergent thermal beam having a predetermined temporal modulation;
(b) an optics assembly having a beam splitter that reflects the divergent thermal beam through a lens with the lens reducing the divergence of the thermal beam to form a substantially collimated thermal beam that impacts a target, the target directing radiation to the optics assembly, and with the lens further focusing and directing the radiation to the beam splitter with the beam splitter passing the radiation on a path away from the light source to form a focused image on a detector, with the radiation passing to the detector having the predetermined temporal modulation,wherein the detector is configured to distinguish a portion of the radiation having the predetermined temporal modulation from a remainder of the radiation in the focused image, the portion of the radiation passing to the detector through the optics assembly; and
(c) a readout integrated circuit, the detector comprising an input signal to the readout integrated circuit and the readout integrated circuit producing a digitally enhanced output signal in response to the receipt of the input signal.

Abstract
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.

11. A radiation detection method, comprising:
-
(a) passing a divergent thermal beam having a predetermined temporal modulation from a light source through an optics assembly having a focus comprising a beam splitter and a lens optically downstream of the beam splitter with the lens substantially collimating the thermal beam; (b) impinging the thermal beam upon a target, the target directing radiation to the optics assembly with the lens focusing the radiation through the beam splitter to form a focused image on a detector, the radiation reflected to the detector having the predetermined temporal modulation; (c) distinguishing the portion of the radiation in the focused image impacted by the thermal beam from a remainder of the radiation in the focused image by detecting portions of the focused image having the predetermined temporal modulation; and (d) displaying an image of at least a portion of the target in response to the distinguishing, at least a portion of the displayed image comprising a digital enhancement corresponding to the predetermined temporal modulation. - View Dependent Claims (12, 13, 14)
