Coherent model-based optical resolution

چکیده
Earlier results on parametric model-based optical resolution by the first author [J. Opt. Soc. Am. A 4, 1402 (1987)] concerned two incoherent sources of known intensity. These results are generalized to sources with any degree of coherence and unknown intensity. A further generalization is that the model underlying the observations and that chosen by the experimenter need not be the same. It is shown how, for a chosen model, observations from which the sources can be resolved can be distinguished from observations from which they cannot. © 1996 Optical Society of America.

Model-Based Optical Resolution
This paper considers the two-point resolution of imaging systems from the viewpoint of model fitting theory. Earlier results have been extended to include (partially) coherent sources of unknown intensity. Furthermore, it is shown how the probability of resolution can be computed. This probability can be used to compare the performance of different imaging systems.
متن کاملModified Structure Function Model Based on Coherent Structures
In the present study, a modified Structure Function was introduced. In this modified Structure Function model, the coefficient of model was computed dynamically base on the coherent structure in the flow field. The ability of this Modified Structure Function was investigated for complex flow over a square cylinder in free stream and a low aspect ratio cylinder confined in a channel. The Results...
متن کاملHigh resolution atomic coherent control via spectral phase manipulation of an optical frequency comb.
We demonstrate high resolution coherent control of cold atomic rubidium utilizing spectral phase manipulation of a femtosecond optical frequency comb. Transient coherent accumulation is directly manifested by the enhancement of signal amplitude and spectral resolution via the pulse number. The combination of frequency comb technology and spectral phase manipulation enables coherent control tech...
متن کاملShape of the Coherent Population Trapping Resonances Registered in Fluorescence
There has been permanent interest in investigations of new magnetic sensors and their various applications (Edelstein, 2007). Last years there is a rapid progress in development of magneto-optical sensors because of their sensitivity and potential for miniaturization. Magnetometers, based on magneto-optical sensors have high sensitivity comparable to, or even surpassing this of the SQUIDs (Supe...
متن کاملApplication of Superresolution Algorithm to Optical Coherent Imaging
The Super-SVA algorithm has been shown effective for improving the resolution of microwave synthetic-aperture radar (SAR) In this paper we review the Super-SVA algorithm and demonstrate its application to optical imaging systems using coherent laser illumination. Examples of such imaging systems include heterodyne-array imaging, holographic laser radar, laser syntheticaperture radar, coherent p...
