Foveated Imaging


3D-Printed Sensor with Eagle Eye

Our customer Prof. Dr. Harald Giessen and his team at the University of Stuttgart have published groundbreaking results from the field of technical optics in Science Advances: The researchers from Stuttgart used Nanoscribe's Photonic Professional GT system to print micro-objective lenses with different focal lengths onto a high-resolution CMOS chip. All images created by the lenses on the chip are simultaneously read out electronically and processed into an image with a significantly improved resolution in the centre.

Previously, it took a large number of cameras and sensors to produce this so-called “foveated imaging”, which, in the automotive industry, for example, had to be installed all around the vehicle. Thanks to this new method it is now possible to produce cameras with sensors that mirror the extra wide field of vision of an eagle's eye. In addition to the automotive industry, the researchers are also envisioning applications for smartphones or in the medical field.
