Revolutionising imaging through an optical fiber the width of a human hair

"through a fibre the width of a human hair... applications in industrial inspection and environmental monitoring... medical imaging... video images from a single multimode optical fibre using a process known as time-of-flight 3D imaging... advanced beam shaping techniques to pattern the input laser light to the fibre to create a single spot at the output. That spot of light then scans over the scene and the system measures the intensity of the backscattered light into another fibre - giving the brightness of each pixel in the image"
