Particle Image Velocimetry (PIV) and optical flow methods represent two cornerstone approaches in experimental fluid dynamics and motion estimation. PIV employs tracer particles seeded in a fluid, ...

A new optical imaging technique holds the potential to greatly improve angioplasty, a surgery commonly performed to treat patients with a partially or completely blocked coronary artery that restricts ...

An international team of researchers has developed an advanced optics system to noninvasively map out the network of tiny blood vessels beneath the outer layer of patients' skin, potentially revealing ...

A newly developed technique uses a Bessel beam to extend the focus of optical coherence microscopy, allowing for a detailed imaging of large sections of the brain. Unlike traditional methods that ...
