"travels through plastic containers, interior walls (not metal/ very thick) reflecting off hidden objects, collected/ feed into algorithm, estimates/ chooses surface most representative of signals received, generates final 3D reconstruction with 96% reconstruction accuracy... overcomes back projection's image resolution too coarse for small items like kitchen gadgets... specularity estimates not just reflection location but also direction... warehouses, airport security scanners, military reconnaissance, human use with AR headset"
