Full-Period Quantum Phase Estimation
Physical Review Letters, 2023Quantum sensing can provide the superior sensitivity for sensing a physical quantity beyond the shot-noise limit. In practice, however, this technique has been limited to the issues of phase ambiguity and low sensitivity for small-scale probe states. Here, we propose and demonstrate a full-period quantum phase estimation approach by adopting the Kitaev'

2004 IEEE International Symposium on Industrial Electronics, 2004
In order to maintain balance, the central nervous system processes information from visual, vestibular and proprioceptive origin and coordinates an appropriate muscle response. A deficiency of sensory inputs or in the central nervous system usually results in balance disorders.

Improving melatonin circadian phase estimates
Sleep Medicine, 2007The quality and quantity of sleep is to a large extent determined by whether the sleep period is in alignment with the most favorable circadian time window for sleep. Misalignment results in compromised sleep. In order to determine this circadian time window, the 24-h profile of melatonin secretion is generally considered to provide the most optimal ...

Two‐phase shelf‐life estimation
Statistics in Medicine, 2001AbstractUnlike most drug products, some drug products must be stored at several temperatures, such as −20°C, 5°C and 25°C, in order to maintain the stability of the drug products. Drug products of this kind are usually referred to as frozen drug products.

Most people are familiar with the global Fourier phase. The shift theorem, describing how the Fourier phase is affected by moving the signal, is common knowledge. The phase in signal representations based on local operations, e.g. lognormal filters, is on the other hand not so well known.

Phase estimation with few photons
Applied Optics, 1984A new algorithm is presented for phase tracking faint low-contrast optical fringes using a proper image photon counter. Simulations show that the tenacity of the new algorithm manifestly surpasses what has been conventionally assumed to be the photon statistical limit. Furthermore, the new algorithm is very quick and easy to compute.

Blind phase shift estimation in phase-shifting interferometry
Journal of the Optical Society of America A, 2007A blind phase shift estimation algorithm that allows simultaneous calculation of phases and phase shifts from three or more interferograms is presented. In phase-shifting interferometry, the phase shift errors introduce specific correlations between the calculated background intensity distribution and the fringe component.

Polynomial Phase Estimation by Least Squares Phase Unwrapping
IEEE Transactions on Signal Processing, 2014Estimating the coefficients of a noisy polynomial phase signal is important in fields including radar, biology and radio communications. One approach attempts to perform polynomial regression on the phase of the signal. This is complicated by the fact that the phase is wrapped modulo 2π and must be unwrapped before regression can be performed.

Amplitude-only versus amplitude-phase estimation
IEEE Transactions on Instrumentation and Measurement, 1990The feasibility of transfer function estimation based on amplitude-only measurements is investigated, and this method is compared with the amplitude-phase (full complex spectrum) method. It is shown that the amplitude-only-based method is a feasible alternative to the full complex spectrum method when the minimum in-phase transfer function of the ...
