Adelaide Researchers Develop Optical Spectrometer with Six-Femtometre Resolution
The Quantum Insider · By Mohib Ur Rehman ·
The Brief
- Researchers led by Adelaide University developed a speckle-based optical spectrometer.
- The device measures light wavelengths at a resolution of six femtometres.
- The team used it to measure the hyperfine structure of rubidium, which the source describes as a first direct measurement.
Why it matters
The work shows that a speckle-based optical spectrometer can resolve very fine wavelength differences, such as rubidium's hyperfine structure, which matters for precision spectroscopy.
