    Miniaturizing medical imaging, sensing technology

    Scientists in Christine Hendon's and Michal Lipson's research groups at Columbia University, New York, have used a microchip to map the back of the eye for disease diagnosis. The interference technology, like bat sonar but using light instead of sound waves , used in the microchip has been around for a little while. This is the first time that technical obstacles have been overcome to fabricate a miniature device able to capture high quality images. Ophthalmologists' current optical coherence tomography (OCT) devices and surveyors' light detection and ranging (LIDAR) machines are bulky and expensive. There is a push for ...
