A method includes imaging, at an imaging resolution, a core of a subsurface formation to create a core image and iteratively performing the following operations until a defined feature of a rock of the subsurface formation exceeds a viewable image feature threshold: extracting a number of subsamples from the core for a first iteration and from each of the number of subsamples previously extracted for a subsequent iteration; increasing the imaging resolution; and imaging each subsample. The method includes performing the following operations for the subsamples last extracted: determining at least one formation property characteristic; determining a guiding rock property for each voxel of the core image and the number of subsample images; and determining a subsample that is a shortest distance to the voxel based on the number of guiding rock properties; and mapping, for each voxel, the at least one formation property characteristic that is the shortest distance.

A DE energy weapon and tracking system includes a passive millimeter wave (PmmW) imaging receiver on a common gimbaled telescope to sense natural electromagnetic radiation from a mmW scene. The PmmW imaging receiver operates in a portion of the electromagnetic spectrum distinct from the IR bands associated with thermal blooming or the HEL laser. In the case of a HPM source, the reflected energy is either in a different RF band and/or of diminished amplitude such as to not interfere with operation of the PmmW imaging receiver. Although lower resolution than traditional optical imaging, PmmW imaging provides a viable alternative for target tracking when the DE weapon is actively prosecuting the target and provides additional tracking information when the DE weapon is not engaged.

Crosstalk mitigation among cameras in neighboring monitored workcells is achieved by computationally defining a noninterference scheme that respects the independent monitoring and operation of each workcell. The scheme may involve communication between adjacent cells to adjudicate non-interfering camera operation or system-wide mapping of interference risks and mitigation thereof. Mitigation strategies can involve time-division and/or frequency-division multiplexing.
