Fast-Fourier-Transform Based Numerical Integration Method For The Rayleigh-Sommerfeld Diffraction Formula
(Optical Society of America, 2006-08-01)
The numerical calculation of the Rayleigh-Sommerfeld diffraction integral is investigated. The implementation of a fast-Fourier-transform (FFT) based direct integration (FFT-DI) method is presented, and Simpson's rule is ...
Frequency-Estimation-Based Signal-Processing Algorithm For White-Light Optical Fiber Fabry-Perot Interferometers
(Optical Society of America, 2005)
A novel signal-processing algorithm based on frequency estimation of the spectrogram of single-mode optical fiber Fabry-Perot interferometric sensors under white-light illumination is described. The frequency-estimation ...
Micro-Air-Gap Based Intrinsic Fabry-Perot Interferometric Fiber-Optic Sensor
(Optical Society of America, 2006-05-01)
A simple intrinsic Fabry-Perot interferometric (IFPI) sensor is developed. The sensor is fabricated by two micro air gaps as reflective mirrors in a fiber to form a Fabry-Perot cavity. Theoretical and experimental studies ...
