Dynamic uncertainty evaluation of axial displacement of optical scanning coordinate measuring machine based on neural network

Yinye Ding, Wenhao Chen, Zeyu Yang, Rencheng Song et autres

Abstract The inner-surface geometry of high-aspect-ratio microholes critically influences the cooling performance of turbine blades in aero-engines. Optical scanning coordinate measuring machines are widely used to inspect such microholes owing to their non-contact operation and high measurement efficiency. During scanning, the axial …

A Model for Quantifying and Propagating Uncertainty of Precise Time Measurement System With Tapped-Delay-Line Time-to-Digital Converters

Xin Yu, Yinye Ding, Wenhao Chen, Rencheng Song et autres

To evaluate the uncertainty of high-performance integrated circuits in precise time-interval measurements, we designed a time-to-digital converter using a typical tapped-delay-line (TDL) architecture implemented on a field-programmable gate array (FPGA). Using a 28-nm Xilinx Kintex-7 FPGA chip, we established a precise time …

An Improved Algorithm to Extract Moiré Fringe Phase for Wafer-Mask Alignment in Nanoimprint Lithography

Feifan Xu, Yinye Ding, Wenhao Chen, Haojie Xia

This paper proposes an improved algorithm based on the phase extraction of the Moiré fringe for wafer-mask alignment in nanoimprint lithography. The algorithm combines the strengths of the two-dimensional fast Fourier transform (2D-FFT) and two-dimensional window Fourier filtering (2D-WFF) to quickly and …
