Focused Laser Differential Interferometry (FLDI) is an innovative, non‐intrusive optical diagnostic tool designed to capture high-resolution density fluctuations within hypersonic flow environments.

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 ...

An intriguing new study argues that current detection methods might be far, far more difficult than they have to be.

The dream of finding life on an alien Earth-like world is hampered by a number of technical challenges. Not the least of which is that the Earth is dwarfed by the size and brightness of the sun. We ...

For most of us, the mention of “technological innovation” brings to mind images of the technologies that have become useful for our everyday lives. We imagine aspiring app developers lounging about ...

Common to optical metrology in many modern systems, the Fizeau design uses a fixed, on-axis coherent point source to illuminate the interferometric cavity. For the most part, it works very well. While ...

Primordial black holes (PBHs) are particularly special types of black hole, thought to have been formed from dense pockets of ...

Scientists have taken a major step toward probing one of physics’ biggest mysteries—how gravity and quantum mechanics fit together—by creating the first unified way to detect tiny “ripples” in ...

Following the selection of The Gravitational Universe by ESA, and the successful flight of LISA Pathfinder, the LISA Consortium now proposes a 4 year mission in response to ESA’s call for missions for ...
