Nature-Artikel: CMOS-Chip von IMS CHIPS als Hologrammprojektor
Scientists at Max Planck Institute for Intelligent Systems and the University of Stuttgart developed an ultrasonic projector for high-resolution moving holographic images. The researchers now report on this in an article in the renowned Nature magazine.
The ultrasound projector is based on a special microchip that was developed and manufactured at Institut für Mikroelektronik Stuttgart. The chip has thousands of tiny gold-plated electrodes, which are arranged as a matrix on the chip surface and can be digitally controlled via electronics integrated in the chip. This way, microbubbles can be generated precisely in liquid above the electrodes, which in turn can be used to spatially modulate ultrasonic waves, resulting in a holographic image impression. Since the so-called “microbubbles” can be switched on and off digitally in rapid succession via the chip, holographic videos can be reproduced with a spatial image impression The original publication can be found on www.nature.com
