High-accuracy wave eld reconstruction: decoupled inverse imaging with sparse modeling of phase and amplitude

چکیده
We apply a nonlocal adaptive spectral transform for sparse modeling of phase and amplitude of a coherent wave eld. The reconstruction of this complex-valued wave eld from Gaussian noisy observations is considered. The problem is formulated as a multi-objective alternating constrained optimization. The developed iterative algorithm decouples the inversion of the forward propagation operator and the ltering of phase and amplitude of the wave eld. It is demonstrated by simulations that the performance of the algorithm, both visually and numerically, is the current state-of-the-art. c ° 2011 Optical Society of America

متن کاملPhase retrieval via SLM phase modulation in 4f optical setup: numerical inverse imaging with sparse regularization for phase and amplitude
1 The 4f optical setup is considered with a wave …eld modulation by SLM (spatial light modulator) located in the focal plane of the …rst lens. Phase as well as amplitude of the wave …eld are reconstructed from noisy multiple intensity observations. The reconstruction is optimal due to a constrained maximum likelihood formulation of the problem. The proposed algorithm is iterative with decouplin...
متن کاملWavefront reconstruction in phase-shifting interferometry via sparse coding of amplitude and absolute phase.
Phase-shifting interferometry is a coherent optical method that combines high accuracy with high measurement speeds. This technique is therefore desirable in many applications such as the efficient industrial quality inspection process. However, despite its advantageous properties, the inference of the object amplitude and the phase, herein termed wavefront reconstruction, is not a trivial task...
متن کاملCompressive sensing computational ghost imaging.
The computational ghost imaging with a phase spatial light modulator (SLM) for wave field coding is considered. A transmission-mask amplitude object is reconstructed from multiple intensity observations. Compressive techniques are used in order to gain a successful image reconstruction with a number of observations (measurement experiments), which is smaller than the image size. Maximum likelih...
متن کاملBackward discrete waveeld propagation modeling as an inverse problem: toward perfect reconstruction of waveeld distributions
1 We consider reconstruction of a wave…eld distribution in an input/object plane from data in an output/di¤raction (sensor) plane. A contribution of this paper concerns both a digital modelling for the forward and backward wave…eld propagation. A novel algebraic matrix form of the discrete di¤raction transform (DDT) originated in [1] is proposed for the forward modelling which is aliasing free ...
