All-Optical Scanning Acoustic Microscope

In this thesis a new instrument, the all-optical scanning acoustic microscope (O-SAM) is presented, it is a non contact scanning acoustic microscope (SAM) which uses lasers to both generate and detect surface acoustics waves (SAWs) The non contact nature of the O-SAM overcomes some difficulties associated with conventional SAMs because of the couplant and surface contact involved. This O-SAM al...

High Resolution Scatterometry by Simultaneous Range/Doppler Discrimination

Several spaceborne scatterometer missions have been successfully flown in the past decade. In addition to the primary mission of measuring ocean surface wind speed and direction, these measurements have proven useful in global scale climate studies of land and ice phenomena as well. A key shortcoming of the scatterometer in these measurements has been the rather coarse spatial resolution availa...

Development of Low CostDeburringSetup with Feedback Capability

To increase productivity and to improve the quality, Automation is a step beyond mechanisation. Automated manufacturing systems includes performing operations such as processing, assembly, inspection, or material handling and combination of more than one of these operations in the same system for reducing the number of distinct production machines or workstations through which the part must be ...

A High Order Approximation of the Two Dimensional Acoustic Wave Equation with Discontinuous Coefficients

This paper concerns with the modeling and construction of a fifth order method for two dimensional acoustic wave equation in heterogenous media. The method is based on a standard discretization of the problem on smooth regions and a nonstandard method for nonsmooth regions. The construction of the nonstandard method is based on the special treatment of the interface using suitable jump conditio...
