Researchers achieve 3D imaging through single optical fibre
A team of scientists, led by the University of Glasgow’s Optics Group, has built a 3D imager able to capture video at 5Hz through a single optical fibre.
The prototype system delivers images through a 40cm long optical fibre, each frame containing up to approximately 4,000 independently resolvable features, with a depth resolution of around 5mm.
By using a pulsed laser, the device also measures the time of flight of the light and hence the range of every pixel in the image. These 3D images can be recorded at distances from a few tens of millimetres to several metres away from the fibre end, with millimetric distance resolution and frame rates high enough to perceive motion at close to video quality.
