Purdue faculty dedicate countless hours to exploring the frontiers of their respective fields, pushing the boundaries of knowledge and contributing to the ever-evolving landscape of academia. To ...

Laser self-mixing interferometry (SMI) harnesses the phenomenon of optical feedback by reinjecting a fraction of a laser’s output back into its cavity. This reinjection leads to an interference effect ...

University of Illinois Physics Professor Paul Kwiat and members of his research group have developed a new tool for precision measurement at the nanometer scale in scenarios where background noise and ...

The researchers fabricated chip-based interferometers (pictured) to measure how light propagating through a magneto-optic material changed in response to a magnetic field. WASHINGTON — Researchers ...

A research team led by Professor Cheol Song at the Department of Robotics and Mechatronics Engineering, Daegu Gyeongbuk Institute of Science and Technology (DGIST), has successfully developed an ...

Zygo is a market leader when it comes to interferometric metrology instrumentation. With two key product lines in that category, Zygo offers an optical profiler and a laser interferometer as well as ...

This experimental setup – based on coherence scanning interferometry – was developed at INRiM. Fiber sensing systems integrate photonic and optoelectronic components that are matched with fiber optics ...

SPIE Photonics West sees the global optics and photonics community come together to present and discuss the latest industry ...

One of the biggest challenges for nanoscale fabrication is how to measure devices on such a minute scale. As the semiconductor industry demands ever smaller devices, the need for reliable, robust ...
