Scanner takes OCT systems to new Capbilities

摘要

Scientists at Vrije Universiteit (VU) Amsterdam developing a realtime scanner that will create a full image of a moving eye without any blurring, have teamed up with photonics hub ACTPHAST 4R for help progressing their scanner concept to a demonstrator stage to acquire data faster than existing optical imaging technologies. The lead researcher on this breakthrough development, Assistant Professor Imran Avci from the Department of Physics and Astronomy at VU Amsterdam, said: "Diagnoses of eye diseases that could lead to blindness require good quality images at an early stage. Eye abnormalities can be so very subtle in the early phase that standard OCT can miss these tiny changes. Because our eyes are constantly moving to refresh the visual input, even at a microscopic level, it makes eye imaging very difficult without having blurred images. Our scanner is different: with the data acquired fast enough, the overall goal is to have a real-time imaging system. The rapid switch will enable us to perform real-time high quality moving footage, or a 'video' of your eye." The scanner works by acquiring data from the light signal at rapid speeds by 'bundling' groups of information together. "Our new scanner will acquire the light signal data at least hundred times quicker than OCT systems that exist today.
