نویسندگان
چکیده
A novel reconstruction method of nanometer micro-displacement Fabry–Perot (F-P) interference is proposed in this study. Hilbert transforms are performed for F-P fringes, and the obtained signal performs tangent operation with original signal. Finally, validity algorithm structure verified by simulation several experimental measurements vibration. Results from experiments show that maximum relative error 4.9%.

Comments on Hilbert Transform Based Signal Analysis
The use of the Hilbert transform for time/frequency analysis of signals is briefly considered. While the Hilbert transform is based on arbitrary continuous signals, most practical signals are digitially sampled and time-limited. To avoid aliasing in the sampling process the signals must also be bandlimited. It is argued that it is reasonable to consider such sampled signals as periodic (this is...
متن کاملShape Reconstruction Based on a New Blurring Model at the Micro/Nanometer Scale
Real-time observation of three-dimensional (3D) information has great significance in nanotechnology. However, normal nanometer scale observation techniques, including transmission electron microscopy (TEM), and scanning probe microscopy (SPM), have some problems to obtain 3D information because they lack non-destructive, intuitive, and fast imaging ability under normal conditions, and optical ...
متن کاملAn angular displacement interferometer based on total internal reflection
This paper describes a new angular displacement interferometer based on the internal-reflection effect. In order to make use of the internal-reflection effect, a novel prism assembly is designed, which yields a very compact optical configuration. As a result, the linearity of the angular displacement interferometer is greatly improved. Both the linearization of the measurement equation and the ...

This paper describes a software based receiver post processor that corrects circularity and gain errors in coherent receivers. The receiver post processor additionally provides range gating capabilities, signal quality estimation, mixer non-linearity detection and various display functions. This paper will concentrate primarily on the identification of circularity errors by the receiver post pr...
متن کاملDouble-Exposure Optical Sectioning Structured Illumination Microscopy Based on Hilbert Transform Reconstruction
Structured illumination microscopy (SIM) with axially optical sectioning capability has found widespread applications in three-dimensional live cell imaging in recent years, since it combines high sensitivity, short image acquisition time, and high spatial resolution. To obtain one sectioned slice, three raw images with a fixed phase-shift, normally 2π/3, are generally required. In this paper, ...
