Photonic Calorimeter

NIST Inventors

Ronald Tosh , Zeeshan Ahmed , Ryan P. Fitzgerald and Nikolai Klimov

The calorimeter uses embedded, nanofabricated photonic sensors to enable micro-scale spatial resolution of dose (energy) distributions and gradients. It presents an alternative to thermistors used in conventional calorimeters for radiation dosimetry, comprising photonic sensors for in-situ dose and

Photonic Dosimeter

NIST Inventors

Ronald Tosh , Zeeshan Ahmed , Ryan P. Fitzgerald and Nikolai Klimov

NIST scientists have developed a photonic device whose resonance characteristics (such as quality factor, peak position, and free spectral range) change in a predictable way in response to the interaction of radiation with the sensor and/or its surroundings. The invention consists of one or more
