- Transmission mode time-reversal super-resolution imagingSean K Lehman
Lawrence Livermore National Laboratory, Livermore, California 94550, USA
J Acoust Soc Am 113:2742-53. 2003..Above and beyond the application of seismo-acoustic imaging, the time-reversal super-resolution theory has applications in ocean acoustics for target location, and ultrasonic nondestructive evaluation of parts...
- Hilbert space inverse wave imaging in a planar multilayer environmentSean K Lehman
Lawrence Livermore National Laboratory, L 154, 7000 East Avenue, Livermore, California 94550, USA
J Acoust Soc Am 117:2929-36. 2005..The data were collected in a multistatic method with no beamforming: all focusing through the multilayer was performed mathematically "after-the-fact," that is, after the data were collected...
- Validation of radiographic simulation codes including x-ray phase effects for millimeter-size objects with micrometer structuresHarry E Martz
Lawrence Livermore National Laboratory, Livermore, CA 94551, USA
J Opt Soc Am A Opt Image Sci Vis 24:169-78. 2007..We conclude that the multislice method is not required for accurate simulation of greater than or equal to 8 keV x-ray radiographs of millimeter-size objects with micrometer structures...
