Large-aperture interferometers are important in the manufacturing and measurement of large-aperture optical elements, which play critical roles in the fields of optical precision manufacturing and ...

Tomography, which involves methods of virtually slicing through three-dimensional structures to generate internal visualizations such as cross-sectional views, has a long history in medicine.

Measurements of biomechanical properties inside living cells require minimally invasive methods. Optical tweezers are particularly attractive as a tool. It uses the momentum of light to trap and ...

Researchers have developed a new optical coherence tomography (OCT) approach that can directly image coordination of tiny hair-like structures known as motile cilia in their natural environment. The ...
