HgCdTe avalanche photodiodes (APDs) are used in mid-wavelength infrared (MWIR) photoelectric detectors in free-space optical communication, three-dimensional light detection, and ranging. Although …
In this paper, a wide measurement range strain sensing method based on phase-accumulation optical frequency domain reflectometry (OFDR) is proposed. Different from the traditional phase demodulatio…
In recent years, Optical Frequency Domain Reflectometry (OFDR) has been able to realize strain measurement with high sensitivity and high spatial resolution (SR) along the sensing fiber. Compared w…
