Single-fiber imaging achieves video-rate speeds for future minimally invasive endoscopy
However, traditional high-resolution endoscopes face severe physical limitations; bulky pixelated detector arrays (like CMOS or CCD) cannot be miniaturized to the hundred-micron scale required to access highly constrained anatomical regions, such as the deep brain, without…
Furthermore, classical reconstruction algorithms suffer from substantial computational latency, making real-time, video-rate image reconstruction impractical. The research demonstrates a novel paradigm in computational imaging that achieves video-rate capture of dynamic scenes while utilizing a spatially non-resolving "zero-dimensional" optical front end consisting exclusively of a single-core optical fiber and a single-pixel photodetector.
