This paper surveys the theory of compressive sampling also known as compressed sensing, or CS, a novel sensing/sampling paradigm that goes against the common wisdom in data acquisition. The CS theory asserts that one can recover certain signals and
基带采样理论概述 The sampling of bandpass signals is discussed with respect to band position noise considerations, and parameter sensitivity. For first-order sampling, the acceptable and unacceptable sample rates are presented, with the practical rates whic
Fluorescence tomography can obtain a sufficient dataset and optimal three-dimensional images when projections are captured over 360? by CCD camera. Herein a non-stop dynamic sampling mode for fluorescence tomography is proposed in an attempt to impro
