It is proposed to extend and generalize the models and reconstruction algorithms of diffraction tomography to cases where the view angles are limited and to the class of hard scattering objects. the required extensions will make use of existing models and theories of diffraction tomography and… More

The problem of estimating radar target parameters such as shape, size and material properties from monostatic scattering measurements is formulated within the context of statistical estimation theory and inverse scattering. a bayesian approach to this problem is proposed where the liklihood ratios… More

It is proposed to determine the feasibility of constructing an electro-optical microscope that has the capability of yielding high quality, quantitative images of three-dimensional semitransparent objects without the need of physically slicing the specimen prior to imaging. the microscope generates… More

The method of phase diversity consists of making two measurements of the image of an unknown extended object at two settings of focus and using these images in a certain least squares error metric to estimate the wave aberration function of an incoherent optical imaging system. in this proposal this… More
