UC Davis electrical engineers have created a chip-sized device to measure the spectrum of visible and infrared light. The spectrometer-on-a-chip could have a wide range of applications in medicine, ...

For decades, the ability to visualize the chemical composition of materials, whether for diagnosing a disease, assessing food quality, or analyzing pollution, depended on large, expensive laboratory ...

For decades, bulky spectrometers have been the main tools for understanding how things are made of chemicals (a thing called composition). Spectrometers are a type of lab equipment that uses prisms or ...

This is a close-up view of the “spectrometer-on-a-chip” technology that could dramatically reduce the size of spectrometers in the future. (Credit: NASA Goddard/Chris Gunn) The Composite Infrared ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2024.240099 discusses an on-chip spectrometer with high performance, low power-consumption and simple control logic. The miniaturized ...

For decades, the ability to visualize the chemical composition of materials, whether for diagnosing a disease, assessing food quality, or analyzing pollution, depended on large, expensive laboratory ...

Resting on a fingertip, this miniature sensor replaces bulky laboratory equipment by using photon-trapping surface nanostructures and artificial intelligence (AI) to accurately analyze disease, check ...
