The A-scan is the amplitude of the echo signal over ToF. The transducer is mounted on the z-axis of the SAM. It can be focused to a specific target layer located in a hard-to-access area by changing the z-position with respect to the sample under testing that is mechanically fixed.
A computer is then used to apply a tomographic reconstruction algorithm to the multiple projections, yielding a 3-D data set. This data set may then be manipulated to show thin slices along any chosen axis of the body, similar to those obtained from other tomographic techniques, such as magnetic resonance imaging (MRI), X-ray computed ...
Netum or Neetum (Greek: Νέητον), was a considerable ancient town in the south of Sicily, near the sources of the little river Asinarus (modern Falconara), and about 34 km southwest of Syracuse. Its current site is at the località of Noto Antica (formerly Noto Vecchio), in the modern comune of Noto .

In nonlinear optics z-scan technique is used to measure the non-linear index n 2 (Kerr nonlinearity) and the non-linear absorption coefficient Δα via the "closed" and "open" methods, respectively. As nonlinear absorption can affect the measurement of the non-linear index, the open method is typically used in conjunction with the closed method ...
