On the other hand, to understand the fine details of how THz interacts with matter, capturing what happens very close to the device’s surface—the “near-field phenomena”—is essential. Existing THz ...

Researchers have developed a new smaller, lighter design for space-based imaging spectrometers with high spectral resolution. These high-dispersion imaging spectrometers could be used onboard ...

The new approach produces extremely accurate and stable frequencies and could significantly enhance precision timekeeping and high-resolution atomic and molecular spectroscopy. WASHINGTON — ...

Spectroscopists are often required to identify an unknown compound from a measured spectrum, verifying sample integrity, and defining detected impurities in a sample. Performing a spectral search can ...

The innovative use of amplified and offset-phase controlled femtosecond-pulse bursts ensures hyper-spectral resolution and rapid spectral acquisition. This advancement not only signifies a significant ...
