Microstructured Optical Fiber for Urban Sensing
A three-core photonic crystal fiber (PCF) anemometer with fast response times (<30μs) for low wind speed (<30m/s) detection is being developed. The results of this investigation are relevant to urban sensing technologies that involve air quality monitoring. High-resolution anemometers with fast response times are important to environmental monitoring industries as well as basic research investigations of small-scale (<10cm) fluid mechanical phenomena. In anemometry, the main difficulty in selecting anemometers is the system size and reliability. The multicore photonic crystal fiber (PCF) anemometer is compact and lightweight unlike the sonic anemometer making it suitable for <10cm resolution measurements. The featured PCF anemometer offers a sensing resolution comparable to hot wire anemometers in the form of a rugged all-weather device. This project was supported in part by the Villanova Undergraduate Research Fellowship Program.
