To advance our understanding, we simulate how three outcrop examples of shear zones (Holsny - Norway, Cap de Creus - Spain, Borborema - Brazil) would look in different types of seismic reflection data using a 2-D PSF-based convolution modelling, PSF (Point-Spread Functions) being the ...
As for any optical system, the observed image Io of a ground based astronomical telescope can be described as a convolution of the geometrical image I with the so-called Point Spread Function (PSF), i.e., (1)Io=I∗PSF. A possible use of the PSF is as a quality measure for the ...

Observed sam- ples (pixels/voxels) in medical images are not direct Dirac impulse measurements of a biological scene, but are typically samples from the convolution of the unob- servable biological scene with an observation kernel, i.e. they have an associated point spread function (PSF). ...
The complex amplitude at the image sensor is given as 2D convolution between Eq. (2) and quadratic phase function \(Q\left( {{1 \mathord{\left/ {\vphantom {1 {z_{h} }}} \right. \kern-\nulldelimiterspace} {z_{h} }}} \right)\) for distance zh. Therefore, the intensity ...
(5) Based on Eq. (5), the intensity on the sensor plane is the convolution between the object hologram and the PSH of the system. Similar to the PSH derived in Eq. (3), the final object hologram is the difference between the two responses recorded by the two camera shots with ...
