Researchers at the Institute of Science Tokyo have developed a neural-network-based 3D imaging technique that can precisely measure moving objects—a task long considered extremely challenging for ...

Optical metrology, as a general-purpose metrology technique that uses light as information carriers for non-contact and non-destructive measurement, is fundamental to manufacturing, basic research, ...

It is a general problem to demodulate 3-D phase information from the recording 2-D intensity distributions in optical metrology. Temporal phase-shifting (TPS) interferometry is the most accurate one 1 ...

In 1948, Dennis Gabor proposed the concept of holography, providing a pioneering solution to a quantitative description of the optical wavefront. After 75 years of development, holographic imaging has ...
