Bubble sizing with a high spatial resolution

IEEE 1988 Ultrasonics Symposium Proceedings., 1990
The authors propose a technique that allows them to size bubbles with the same accuracy as with the double-frequency method and to locate them with the same range resolution as with the pulsed Doppler velocimeter. They demonstrate that the signal scattered by the bubble insonified by a high-frequency pulsed ultrasonic field and a low-frequency pumping ...

Spatial resolution improvement of a low spatial resolution image using spatial component extracted from high spatial resolution images

Proceedings of IGARSS '93 - IEEE International Geoscience and Remote Sensing Symposium, 2002
This method consists of two parts: extraction of the high spatial resolution from high spatial resolution visible and near-infrared images, reconstruction of the high resolution image from a low resolution image using extracted high resolution spatial information.

Asteroseismology with A Spatial Resolution

2000
One of the main objectives of the detailed study of the spectra of excited modes in main sequence pulsating stars is the unique opportunity to apply, similar to helioseismology, the inverse techniques for investigation of a star’s inner structure. Numerous sets of detected and (ι,m,n) — identifiednormal nonradial modes is crucial for the application of

Collimator Spatial Resolution

IEEE Nuclear Science Symposium Conference Record, 2005, 2006
Pixellated detectors based on cadmium-zinc telluride (CZT) are a promising alternative to NaI-based SPECT cameras. The performance of either system is quantitatively described in terms of resolution and sensitivity. This investigation is based on an analytical model published earlier, describing SPECT collimators according to the NEMA definitions of ...
