New optical method paves way to breath test for cancer biomarker

Researchers have developed an extremely sensitive, yet simple optical method for detecting formaldehyde in a person's breath. Because formaldehyde is being studied as a potential biomarker for lung and breast cancer, the ...

Imaging light waveforms in air plasma

An international team that includes physicists at LMU has developed a new method with which to characterize the ultrafast oscillation of the electrical fields associated with light.

Sensors and metrology as the driving force for digitalization

Many digitalized processes depend on data collected by increasingly powerful sensors and other test and measurement technology. When this data is processed, it provides precise and reliable information about the operating ...

New super-accurate optical atomic clocks pass critical test

Researchers have measured an optical clock's ticking with record-breaking accuracy while also showing the clock can be operated with unprecedented consistency. These achievements represent a significant step toward demonstrating ...

New discovery improves use of optical tweezers

This year's Nobel Prize in Physics, awarded for discoveries in laser physics, recognizes optical tweezers. Now researchers from the University of Gothenburg have developed a method that greatly simplifies and improves the ...
