...are remarkable, and they are able to achieve the highest resolutions theoretically possible (researchers are able to observe and measure topographic details on 500 nanometer grooves). In my research work, the laser scanning confocal microscope is one of the most useful optical measuring systems...

...of automotive safety glass. where certain topographic characteristics are required to assure adhesion between glass and film layers. However, such measurement is quite slow, and irregular spacing between points within a profile and between. the multiple traces makes 3D parameter calculation difficult...

Made for use with sub-0.25- um processes, the SEMVision in-line microscope automatically classifies up to 300 defects per hour. The system uses a proprietary technology to provide enhanced topographic information and automatic classification of defects into types closely linked to their source...

...to generate a topographic, or height, profile of the sample. ADwin systems are ideal for these applications. The ADwin - which incorporates digital and analog inputs and outputs with a real-time processor in a single unit - can drive stepper motors and/or other actuators, using feedback from various...

Topographic Mapper laser system, the glacier was slightly thickening between 1991 and 1999, before it started to thin rapidly. Current thinning rates have reached 12 meters (about 39 feet) per year. That 's probably because the Jakobshavn Glacier, which was flowing at 7 kilometers (about 4.4 miles) per...

...of an Other topographic features inspected by this system include. airstream for imaging and measurement of retinal topography. macula holes, tumors, edema and more. The software offers. The light probe is nearly undetectable by the patient and images eight different color scales, ten image enhancement...

) Figure 2. In an optical profiler, a digital camera records fringes that result from reflections off a test surface and a reference surface. The system converts these fringes into high-resolution topographic information. The white-light interferometer is a type of microscope in which the two waves...

Accessories for two-dimensional topographic mapping over intermediate distances are also available. When used in conjunction with a microscope, the spatial resolution can be reduced from approximately 400 um down to 1 um. Figure 3: A close up of Tyvek 's surface texture and the overlying metal...

...surface elevation data by using NASA's Airborne Topographic Mapper, a scanning lidar system. Those results can be compared to ICESat's data to see how well the new lidar system is working. The Dry Valleys area presents special challenges for lidar measurements, Csatho explained. There, the exposed...

...that the surface. atomic configuration as defined by the crystal ographic orientation helps determine the localized. work function. Figure 3 - Kelvin Probe Force Microscopy measurement of a CGS film showing (a) topographic image with facets. (b). Representation of the measured work function with crystal ographic...
