Dynamic speckle analysis is a non‐invasive optical technique that exploits the fluctuating interference patterns produced when coherent light, typically from lasers, illuminates a dynamic sample.

The scattered light forms a continuously fluctuating speckle pattern, which passes through a lens and onto a CMOS image sensor within the catheter. Using a linked high-speed camera, it's possible to ...

The challenge of recovering image data from objects hidden from direct observation or concealed by corners, termed non-line-of-sight imaging (NLoS), can be tackled in several ways, often involving ...
