Dual electro-optic frequency comb photonic thermometry
Adam J. Fleisher, Zeeshan Ahmed, Tobias Herman +1
We report a precision realization of photonic thermometry using dual-comb spectroscopy to interrogate a -phase-shifted fiber Bragg grating. We achieve read-out stability of 7.5…
Towards Replacing Resistance Thermometry with Photonic Thermometry
Nikolai Klimov, Thomas Purdy, Zeeshan Ahmed
Resistance thermometry provides a time-tested method for taking temperature measurements that has been painstakingly developed over the last century. However, fundamental limits to…
Optofluidic Temperature and Pressure Measurements with Fiber Bragg Gratings Embedded in Microfluidic Devices
Gregory A. Cooksey, Zeeshan Ahmed
The integration of photonic sensors into microfluidic devices provides opportunities for dynamic measurement of chemical and physical properties of fluids in very small volumes. We…
