Applecation of wavelet transform to enhancing the vertical resolution of density log curves;

Multi-frequency weighting reconstruction of the original GR signals with optimum wavelet base shows that the vertical resolution of GRT curves is improved,so it provides high quality logging data for reservoir assessment.

For improving the vertical resolution of LWD wave propagation resistivity, a data processing method based on wavelet transform is put forward.

The key technologies of OCT for ophthalmic imaging were discussed and the method for further improvement of longitudinal resolution of OCT was proposed.

This article analyzes the two primary performance parameters (noise, longitudinal resolution) of spiral CT.

By utilizing this system, the practical OCT image for sample collection of tomato tegument is obtained, gaining a longitudinal resolution of about 10μm.

For a confocal microscope with a finite-sized detector,the improvement in axial resolution by a phase-only filter with two zones was experimentally investigated.

Based on vector diffraction theory, a new kind of tunable binary annular filters applied to high numerical aperture objectives is designed, and how to decide annular radius in order to increase axial resolution is discussed.

For this,to improve conventional curve resolution,the logging evaluation technique for thin layer was used,such as vertical resolution matching,deconvolution,and α factor method.

An analysis of longitudinal resolution in spiral CT;

To improve the longitudinal resolution by overlapping slice reconstruction.
