Infrared Detector for Smartphones and Autonomous Vehicles

Switching between different wavelengths

19-Aug-2021 - Jülich researchers, together with Italian and German colleagues, have developed a particularly cost-effective infrared detector that can be easily integrated into existing camera chips and smartphones. The new sensor can make two technically important ranges of infrared radiation visible, which ...

“Honey, I shrunk the detector”

Researchers have developed the world’s smallest ultrasound detector

18-Sep-2020 - Researchers at Helmholtz Zentrum München and the Technical University of Munich (TUM) have developed the world’s smallest ultrasound detector. It is based on miniaturized photonic circuits on top of a silicon chip. With a size 100 times smaller than an average human hair, the new detector can ...

How small is the proton?

International team of researchers observes unexpectedly small proton radius in a precision laser experiment with exotic hydrogen atoms

12-Jul-2010 - The proton - one of the universal building-blocks of all matter - is even smaller than had previously been assumed. This is the result obtained at the Paul-Scherrer-Institut (PSI) in Villigen (Switzerland) by an international research team, including scientists from the Max Planck Institute of ...

Checking people at airports with terahertz radiation

PTB succeeds in absolute measurement of terahertz radiation

22-Sep-2008 - Within the last few years the number of transport checks – above all at airports – has been increased considerably. A worthwhile effort as, after all, it concerns the protection of passengers. Possibilities for new and safe methods of transport checks are offered by terahertz radiation. Before ...
