Optical barcodes expand range of high-resolution sensor

The same geometric quirk that lets visitors murmur messages around the circular dome of the whispering gallery at St. Paul's Cathedral in London or across St. Louis Union Station's whispering arch also enables the construction ...

A molecular fingerprint beyond the Nyquist frequency

Ultrashort pulses play a significant role in spectroscopic applications. Their broad spectral bandwidth enables simultaneous characterization of the sample at various frequencies, eliminating the need for repeated measurements ...
