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 ...

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 ...

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 ...

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 ...

Optical interferometers work by splitting light into two paths and then recombining those paths. By placing the magneto-optic material in one of the paths, the researchers were able to measure whether ...

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 ...

We suspect there are three kinds of people in the world. People who have access to a Michelson Interferometer and are glad, those who don’t have one and don’t know what one is, and a ...

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 ...

When designing materials and structures at the nanoscale, it is important to be able to characterize and measure them. Getting tools to measure on these very small length scales can be challenging as ...

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 ...
