A laser spot tracker device comprising a laser tracker receiver using a quadrant detector incorporated into a pair of binoculars or optical telescope system with a crosshair or reticule. Directional information from the laser tracker receiver is displayed to an operator (JTAC) to allow the reticule
A laser spot tracker device comprising a laser tracker receiver using a quadrant detector incorporated into a pair of binoculars or optical telescope system with a crosshair or reticule. Directional information from the laser tracker receiver is displayed to an operator (JTAC) to allow the reticule to be manually steered on to the target illuminated by the laser, thus identifying the target to the spotter. The laser code may be pre-selected to track a particular designator, or, the tracker may read out the code or codes of laser spots within its field of view.

What is claimed is: 1. Method of verifying that a target is being illuminated by a laser from a designator comprising: providing a composite device, separate from either of the designator or the target, comprising an optical portion having a field of view for viewing the target in the field of view
What is claimed is: 1. Method of verifying that a target is being illuminated by a laser from a designator comprising: providing a composite device, separate from either of the designator or the target, comprising an optical portion having a field of view for viewing the target in the field of view, and a opto-receiver portion for receiving scattered laser light; viewing the target in the field of view of the composite device; and displaying information in the field of view of the composite device about a direction of the received laser light from the target; wherein displaying information about the direction comprises: providing at least one set of quadrant arcs in the field of view, and selectively illuminating the quadrant arcs to indicate the direction of the received laser light in relation to the target; wherein providing at least one set of quadrant arcs in the field of view comprises: providing a set of inner quadrant arcs, and illuminating appropriate ones of the inner arcs when the received laser light is close to a center of the field of view; and providing a set of outer quadrant arcs, and illuminating appropriate ones of the outer arcs when the received laser light is far from the center of the field of view. 2. The method of claim 1, further comprising: when viewing the target, centering the target in a reticule in the field of view. 3. The method of claim 1, wherein displaying information about the received laser light comprises: displaying information about intensity of the received laser light in the field of view. 4. The method of claim 1, wherein the laser light is encoded using a pulse coding system to ensure that a specific seeker and designator combination work in harmony, and wherein displaying information about the received laser light comprises: displaying the code in the field of view. 5. The method of claim 4, wherein multiple targets are laser-illuminated by multiple designators, each having a unique code, and further comprising: tracking the multiple designators in the field of view, and toggling through the designators. 6. The method of claim 5, wherein: in a first mode of operation, only outputting information that matches a given code; and in a second mode of operation, outputting information that matches any allowed code description and allowing the user to select a code description, after which only information matching the selected code is output. 7. The method of claim 1, wherein: the optical portion includes a reticule centered in the field of view. 8. Apparatus for viewing a target and determining a direction and distance of a spot of received laser light comprising: a visual system, separate from either the target or a source of the laser light, comprising viewing optics for viewing a scene which contains the target; an electronic system for collecting the received laser light with a segmented detector capable of sensing an angle of the spot of received laser light; means for generating information pertaining to a distance and direction of the spot of received laser light from the target; and display means for superimposing the information onto a view of the scene which contains the target; wherein the display means comprises: a set of inner quadrant arcs which, when illuminated, indicate that the received laser light is close to a center of the field of view; and a set of outer quadrant arcs which, when illuminated, indicate that the received laser light is far from the center of the field of view. 9. The apparatus of claim 8, wherein: the display means indicates a direction to move to a null, which is boresighted with a reticule in the viewing optics to superimpose crosshairs onto and therefore identify the far-field target from which the laser radiation is coming. 10. The apparatus of claim 8, further comprising: a decoder to selectively track laser pulse trains with a pre-determined code. 11. The apparatus of claim 10, further comprising: logic to identify the codes in use within the view, and means for selecting a chosen code (designator) to track. 12. The apparatus of claim 10, further comprising: means for indicating signal strength of the received laser light. 13. The apparatus of claim 8, wherein: the means for generating information pertaining to a distance and direction comprises a segmented detector; and the segmented detector comprises an avalanche quadrant detector to detect laser radiation. 14. The apparatus of claim 13, further comprising: a high-voltage bias power supply adjustable as a function of background light to maintain the detector at a bias point for optimum signal-to-noise ratio. 15. A method of verifying that a target has been illuminated by a laser designator for illuminating objects with laser light comprising: viewing the target with an optical portion of a device, in a field of view of the device, wherein said device is separate from the laser designator; providing indications, in the field of view of the device, about a direction and distance of laser light scattered from an object which has been illuminated by the laser designator with respect to the target; wherein the indications comprise: providing a set of inner quadrant arcs, and illuminating appropriate ones of the inner arcs when the received laser light is close to a center of the field of view; and providing a set of outer quadrant arcs, and illuminating appropriate ones of the outer arcs when the received laser light is far from the center of the field of view. 16. The method of claim 15, wherein the indications comprise: at least one set of quadrant arcs are selectively be illuminated to serve as steering commands for re-aiming the optical device. 17. The method of claim 15, further comprising: displaying at least one of a code associated with the received laser light and a signal strength of the received laser light.
