Science Daily May 26, 2022 Many modern imaging sensors must obtain multiple looks or “views” of a target at different orientations to automatically classify it with high confidence. Therefore, when tasked with classifying many targets, a mobile sensor may need to travel a long distance to change its position and orientation relative to every target, resulting in costly and time-consuming operations. A team of researchers in the US (Cornell University, Naval Surface Warfare Center) has developed a new approach, referred to as informative multiview planning (IMVP) that simultaneously determines the most informative sequence of views and the shortest path between […]

Engineers combine light and sound to see underwater
Science Daily November 30, 2020 High-resolution imaging and mapping of the ocean and its floor has been limited to less than 5% of the global waters due to technological barriers. Researchers at Stanford University present a proof-of-concept system which bridges the gap between electromagnetic imaging in air and sonar imaging in water through the laser-induced photoacoustic effect and high-sensitivity airborne ultrasonic detection. They used air-coupled capacitive micromachined ultrasonic transducers which is a critical differentiator from previous works and has enabled the acquisition of an underwater image from a fully airborne acoustic imaging system. There is much promise for the scalability […]
