“…High-resolution features that are compromised by increasing the depth of field can be reconstructed computationally [51], for example by applying a speckle pattern [52]. Fusing data from single-photon cameras and CCDs can build on the time resolution of the former and the high pixel count of the latter [53]. Single-photon cameras are also capable of distinguishing depth layers many km from the object [54] [55].…”

Micro-reactors (i.e., very small transportable or mobile nuclear reactors with a capacity less than 20 MWt) are being developed to supply heat and power for various applications in remote areas, military installations, emergency operations, humanitarian missions, and disaster relief zones. A wide variety of reactor types are under consideration, including sodium-cooled fast reactors, molten salt reactors, light water reactors, very-high-temperature gas reactors, and heat pipe reactors. These miniaturized transportable reactor designs remain largely untested and unproven. System and component testing are needed to demonstrate design safety and system robustness, reliability and efficiency. 2. Concept of Operations for Instrumentation for the non-nuclear micro-reactor test bed.

“…The most common approach to image formation is obvious and intuitive: a light source illuminates the scene, and the backreflected light is imaged with lenses onto a detector array (a camera). A second paradigm, single-pixel imaging, relies instead on the use of a single pixel for light detection, while the structure is placed in the illumination by spatially scanning the scene in some form [1][2][3][4][5][6]. Three-dimensional (3D) imaging can be obtained with these approaches, gathering depth information via stereovision, holographic, or time-of-flight (ToF) techniques [7][8][9][10].…”

Traditional paradigms for imaging rely on the use of a spatial structure, either in the detector (pixels arrays) or in the illumination (patterned light). Removal of the spatial structure in the detector or illumination, i.e., imaging with just a single-point sensor, would require solving a very strongly ill-posed inverse retrieval problem that to date has not been solved. Here, we demonstrate a data-driven approach in which full 3D information is obtained with just a single-point, single-photon avalanche diode that records the arrival time of photons reflected from a scene that is illuminated with short pulses of light. Imaging with single-point time-of-flight (temporal) data opens new routes in terms of speed, size, and functionality. As an example, we show how the training based on an optical time-of-flight camera enables a compact radio-frequency impulse radio detection and ranging transceiver to provide 3D images.
