Point-Wise Phase Estimation Method in Fringe Projection Profilometry under Non-Sinusoidal Distortion [PDF]

open access: yesSensors, 2022
In fringe projection profilometry, high-order harmonics information of distorted fringe will lead to errors in the phase estimation. In order to solve this problem, a point-wise phase estimation method based on a neural network (PWPE-NN) is proposed in ...

Pulse Accumulation Approach Based on Signal Phase Estimation for Doppler Wind Lidar [PDF]

open access: yesSensors
Coherent Doppler wind lidar (CDWL) uses transmitted laser pulses to measure wind velocity distribution. However, the echo signal of CDWL is easily affected by atmospheric turbulence, which can decrease the signal-to-noise ratio (SNR) of lidar. To improve

Imperfect Distributed Quantum Phase Estimation [PDF]

open access: yesComputational Science – ICCS 202020th International Conference, 2020
In the near-term, the number of qubits in quantum computers will be limited to a few hundreds. Therefore, problems are often too large and complex to be run on quantum devices. By distributing quantum algorithms over different devices, larger problem instances can be run.

Amplitude estimation without phase estimation [PDF]

open access: yesQuantum Information Processing, 2020
AbstractThis paper focuses on the quantum amplitude estimation algorithm, which is a core subroutine in quantum computation for various applications. The conventional approach for amplitude estimation is to use the phase estimation algorithm, which consists of many controlled amplification operations followed by a quantum Fourier transform.

A digital phase‐based on‐fly offset compensation method for decision feedback equalisers

open access: yesIET Circuits, Devices and Systems, 2021
A low‐complexity method to reduce the offset voltage of dynamic comparators employed as samplers in decision feedback equalisers (DFE) is introduced. The authors propose the phase‐domain offset reduction technique (PORT), which leverages an all‐digital ...
