Many existing systems for three-dimensional (3D) shape measurement require mechanical moving parts that limit the measurement speed. A non-contact optical system that does not requires any moving parts can, in principle, increase the speed of meas...
Metrology is the science of measurement and deals with measuring different physical aspects of objects. In this research the focus has been on two basic problems that metrologists encounter. The first problem is the trade-off between the range of ...
GELAREH BABAIE. Dynamic range enhancement in digital fringe projection and laser interferometry. (Under the direction of DR. FARAMARZ FARAHI)Optical metrology is the science and technology concerning measurements with light. Surface texture and 3D...
Fringe projection technique has been a powerful tool for 3D metrology and surface profilometry with high repeatability. However, for in-situ measurement of objects with highly specular surfaces, large dimensions, and large varying slopes, acquirin...
Non-null interferometry offers a viable alternative to traditional interferometric testing of aspheric micro-lenses since computer generated holograms or null optics whose fabrication and testing are very expensive, are not required. However, due ...
In the field of optical metrology, there are many existing techniques for measurement of the surface profile or film thickness of a sample of interest. However, many of these common techniques break down when there exists a high level of noise in ...
