Gridlocking and correlation methods and arrangements

An apparatus, comprising:

• a display to receive a reference image and a comparison image to display as coherent images, the reference image based upon a first track about a first object and the comparison image based upon a second track about a second object sensed substantially simultaneously with the first track;
• an optical correlator coupled with said display to output an interference intensity substantially proportional to a cross-correlation of the reference image with the comparison image;
• a detector coupled with said optical correlator to detect the interference intensity;
• and
• a comparator coupled with said detector to associate the first object with the second object based upon the interference intensity and a second interference intensity, wherein the second interference intensity is substantially proportional to a cross-correlation of the reference image with a second comparison image.

A machine-readable medium containing instructions, which when executed by a machine, cause said machine to perform operations, comprising:

• receiving a reference image and a comparison image, wherein the reference image comprises track data of a first track about a first object and the comparison image comprises track data of a second track about a second object, the first track sensed substantially simultaneously with the second track;
• displaying the reference image and the comparison image as coherent images at the input plane of an optical correlator;
• detecting an interference intensity substantially proportional to a cross-correlation of the reference image with the comparison image;
• and
• associating the first object with the second object based upon a comparison of the interference intensity with a second interference intensity, wherein the second interference intensity is substantially proportional to a cross-correlation of the reference image with a second comparison image.
