Confocal White Light Microscopy

Non-contact optical techniques for 3D surface data acquisition like short coherence (white light) interferometry, optical profilers or fringe projection are well established for applications with low surface complexity, where the average surface roughness amplitude is small and neglectable compared to the form amplitudes or where the aspect ratios of amplitudes and spacings are small. In genera...

Natural Interaction White Paper

But what about the second one, calm technology? It is about interaction design, poetry, perception, quality, and it is almost completely unrealized. It is about much more subtle properties than quantities, miniaturization and wireless networking. Google returns less than 50 thousands results on the subject. The world forgot the most precious heritage of Weiser. This text is about calm technolog...

New light on white matter.

Injury of central white matter is a major cause of functional disability in cerebrovascular disease. White matter is a target of hypoxic-ischemic injury throughout life, in clinical settings ranging from periventricular leukomalacia in the neonatal period, stroke and cardiac arrest in adults, to vascular dementia in the aging brain. The traditional view from animal studies is that gray matter i...

Moiré interferometry with white light.

While high-sensitivity moiré interferometry requires monochromatic light, an auxiliary compensator grating removes the requirement. Experimental verification utilized white light for moiré interference of sensitivity 0.833 microm/fringe. Configurations readily amenable to compensation include moiré fringe multiplication by even factors and the minimum-deviation arrangement. Chromatic compensati...
