optical tomography

The first ever optical coherence tomography (OCT) images of cubic meter volumes have been produced, through an industry-academic collaboration. The advance could open up many new uses for OCT in industry, manufacturing and medicine. It also marks a milestone toward developing a high-speed, low-cost optical coherence tomography system on a single integrated circuit chip. James [...]

Engineers will need a 3-dimensional image depicting how light interacts with objects on the nanoscale in order to design the next generation of optical devices, from efficient solar panels to LEDs to optical transistors. But the physics of light has thrown up a roadblock in traditional imaging techniques: the smaller the object, the lower the [...]
