Traditional chemical detection tools are slow and bulky, often needing mechanical parts that wear out. They also struggle to measure many chemical signals at once.
This invention uses lasers and modulators to create special light waves called “optical frequency combs” that can scan multiple chemical features instantly. These combs detect chemicals by analyzing how light changes as it interacts with different substances. It’s fast, accurate, and doesn’t need moving parts like older systems. The result is a detailed chemical fingerprint of whatever is being tested.
