First, images of the laser profile must be collected at a fast frame rate to maintain a high resolution in the forward direction.
For the purpose of this study we've focused primarily on a data flow in a typical obstetrics US scan, performed in B-Mode, with spatial resolution of 256×256, maintaining a contrast resolution of 8 bits (256 shades of gray).
Beyond the limit where optical focusing is not effective, acoustic-resolution PAM (AR-PAM) takes advantage of the much lower acoustic scattering to maintain a high lateral resolution via focused acoustic detection.
To maintain a high spatial resolution of ∼1 mm when examining each plane, a two-block approach is employed combining data from two fields of view to reconstruct the whole flow field.
It will be shown how the coherent application of the procedure allows us to develop high-order accurate Finite Volume upwind schemes, which maintain a good spectral resolution in the entire range of resolved scale.
From this point in his pondering and through to his final designs his main goal was to find a method to overcome this limitation and to maintain a much higher resolution.
In viscous flow computations a modified Jameson's sensor (Ducros et al., 1999 [61]) limits the AV to small values in viscous shear regions, so as to maintain a high-order resolution in smooth regions and an essentially non-oscillatory behavior near sharp gradients/shocks regions.
In the case of the proposed system, because of the use of large sample windows, the CCV maintains a high resolution even with small array sizes.
Dynamic cases with moving interfaces show the new method is capable of maintaining a desired resolution near the interface with an acceptable number of relaxation iterations per time step, which demonstrates the method's potential to be used as a mesh relaxer for arbitrary Lagrangian Eulerian (ALE) methods.
We should also note that, with larger area sensors, the imaging FOV of this platform can be even further increased while maintaining a similar resolution level.
