Jan 3, 2011 · Apodization is defined as a signal processing strategy that reduces the contribution of outer elements in an array by applying weighting functions, such as Gaussian or Hamming, during …

Apodization refers to the process of multiplying a signal, such as a free induction decay (FID), with a window function to force its intensity to zero, thereby eliminating distortions during Fourier …

An apodization function acts to remove ringing artifacts in a FTS-derived radiance spectrum that arise from a finite path difference, but it comes at the cost of a slight reduction in spectral resolution (Liu …

Mar 1, 2026 · Additionally, the OATS apodization weights were physically interpretable and learned to emulate image formation parameters such as time-gain compensation, F-number limited aperture, …

Feb 1, 2014 · Apodization techniques were first introduced with surface acoustic wave (SAW) transducers in order to improve the sampling of the signal coming from an unapodized SAW device …

Oct 1, 2006 · The influence of noise on the standard deviation of spectral integrals is examined. Calculations assuming discrete Fourier-transform data are compared…

Dec 1, 2025 · This study addresses the limitations of pulse energy threshold constraints and insufficient adjustment range inherent in point-by-point (PbP) inscription techniques relying solely on refractive …

Apr 1, 2017 · Apodization is a common way to control the sidelobe level of the beampattern. To design the apodization, it is usually assumed that the medium is homo…

Oct 1, 2024 · This paper proposes an ultrasound imaging algorithm based on sub-beamformer and multi-apodization with cross-correlation (SUB-MAX), aiming to achieve high resolution close to the …

Apodization requires that the refractive index modulation at the edges of the grating gradually disappear. As described in Section 5.2.1, a moiré grating is composed of two individual gratings, which leads to …
