PAINTER: a spatio-spectral image reconstruction algorithm for optical interferometry
Astronomical optical interferometers sample the Fourier transform of the intensity distribution of a source at the observation wavelength. Because of rapid perturbations caused by atmospheric turbulence, the phases of the complex Fourier samples (visibilities) cannot be directly exploited. Consequently, specific image reconstruction methods have been devised in the last few decades. Modern poly...
متن کاملOptimal Image Reconstruction in Radio Interferometry
We introduce a method for analyzing radio interferometry data which produces maps which are optimal in the Bayesian sense of maximum posterior probability density, given certain prior assumptions. It is similar to maximum entropy techniques, but with an exact accounting of the multiplicity instead of the usual approximation involving Stirling’s formula. It also incorporates an Occam factor, aut...
متن کاملdiffuse optical tomography: image reconstruction and verification
introduction: in this study, we intend to use diffuse optical tomography (dot) as a noninvasive, safe and low cost technique that can be considered as a functional imaging method and mention the importance of image reconstruction in accuracy and procession of image. one of the most important and fastest methods in image reconstruction is the boundary element method (bem). this method is introdu...
متن کامل3-D Image Reconstruction in Optical Tomography
The Problem: Optical tomography (OT), as a potential diagnostic tool for detecting growths in translucent soft tissue, has been proposed and studied by several groups in recent years. Its principle is to use multiple movable light sources and detectors attached to the tissue surface to collect information on light attenuation, and to reconstruct the internal 3-D absorption and scattering distri...
متن کاملOptical Interferometry
■ Abstract The field of optical and infrared (IR) interferometry has seen rapid technical and scientific progress over the past few years. A number of instruments capable of precise visibility measurements have been built, and closure-phase imaging with multitelescope arrays has been demonstrated. Astronomical results from these instruments include measurements of stellar diameters and their wa...
