Phase Difference Measurement Based on Recursive DFT with Spectrum Leakage Considered
This paper investigates spectrum leakage influence on the performance of discrete Fourier transform (DFT) based phase difference measurement and proposes a novel method with spectrum leakage considered. In the proposed method, spectrum is firstly corrected by interpolation algorithm to remove the influence of short range leakage. To avoid negative frequency interference caused by the long range...
متن کاملMoiré Fringe Phase Difference Measurement Based on Spectrum Zoom Technology
Grating displacement measurement technique is an important means to achieve precise displacement measurement of nanometer scale. Moiré fringe phase difference measurement is the basis of grating displacement measurement technique. Traditional Moiré fringe subdivision method based on DFT algorithm has low frequency resolution relatively when extracting Moiré fringe fundamental frequency spectral...
متن کاملConsumption-Based Asset Pricing with Recursive Utility
In this paper it has been attempted to investigate the capability of the consumption-based capital asset pricing model (CCAPM), using the general method of moment (GMM), with regard to the Epstien-zin recursive preferences model for Iran's capital market. Generally speaking, recursive utility permits disentangling of the two psychologically separate concepts of risk aversion and elasticity of i...
متن کاملCMOS Sum & Difference Imager with On-Chip Charge-Leakage Compensation
This paper presents a new technique for implementing a low-power CMOS imager with simultaneous on-chip computation of the difference and sum of two successive frames. Existing difference imagers are susceptible to errors due to collection (by the sense element and in-pixel storage node) of photo-generated charge that diffuses from the photo-active pixel area during integration of the second fra...
متن کاملHigh-accuracy measurement of cladding noncircularity based on phase velocity difference between acoustic polarization modes.
A high-accuracy measurement method for the noncircularity (ellipticity) of silica glass fibers is demonstrated. This method makes use of the phase velocity difference between two eigen polarization modes of the lowest-order acoustic flexural wave in an optical fiber. The relationship between the acoustic phase velocity difference and the fiber ellipticity is formulated. Three types of optical f...
