A hybrid opto-microelectromechanical, coherent laser light, single-detector imaging system is demonstrated that applies compressive sensing algorithms for computational imaging of wavefield intensity from a small number of projective measurements of the field. The projective measurements are implemented using spatial light modulators of the digital(More)
The target position information contained in scattering data is explored in the context of the scalar Helmholtz operator for the basic twopoint scatterer system by means of the statistical estimation framework of the Fisher information and associated Cramér-Rao bound (CRB) relevant to unbiased position estimation. The CRB results are derived for the exact(More)
A Cramer-Rao bound (CRB) study is developed in onedimensional (1D) space which sheds fundamental insight onto the information about multiply scattering point-like scatterers that is contained in scattering field data corresponding to transmissive, reflective, and combined transmissive plus reflective sensing geometries, and singleand multi-frequency(More)
A Cramer-Rao bound (CRB) study is developed to characterize the information content about scattering parameters that is contained in reflective (R), transmissive (T), and combined R plus T wave scattering data. The analysis is developed for scalar wave scattering systems in onedimensional space, paying particular attention to elastic scatterers, which(More)
