High-harmonic interferometry can be used to measure ... from femtoseconds down to attoseconds over a broad spectral region. Imaging a chemical reaction requires various tools to be exploited.

What's on and in a star? What happens in an active galactic nucleus? Answering those questions is the goal of a proposed ...

Now, applied physicists at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have invented a new type of interferometer that allows precise control of light’s frequency, ...

To explore these topics, we utilize a wide range of innovative techniques such as point spread function engineering, differential interferometry, multiplexed optical scanning, computational imaging, ...

Researchers have simplified a highly complex quantum imaging technique, 2DES, used to observe ultrafast electron interactions. By refining an existing interferometer design, they improved control over ...
