Earth's atmosphere is an impediment to astronomical observations. Not only is cloudy weather a problem, but temperature fluctuations in the atmosphere mean that ground-based telescopes require ...

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 ...

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 ...

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 ...

Hypertelescope capable of direct high-resolution imaging with a high limiting magnitude have been built and tested on Earth. The Hypertelescope group have proposed giant telescopes 10-25 kilometers ...

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 ...
