Near-Field Optical Reflective Sensing for Bow Tracking

This paper explores the potential of near-field optical reflective sensing for musical instrument gesture capture. Near-field optical sensors are inexpensive, portable and nonintrusive, and their high spatial and temporal resolution makes them ideal for tracking the finer motions of instrumental performance. The paper discusses general optical sensor performance with detailed investigations of ...

Apertureless near-field optical microscope

We demonstrate a new method whereby near-field optical microscope resolution can be extended to the nanometer regime. The technique is based on measuring the modulation of the scattered electric field from the end of a sharp silicon tip as it is stabilized and scanned in close proximity to a sample surface. Our initial results demonstrate resolution in the 3 nm range--comparable to what can be ...

Enlarged near-field optical imaging

Near-Field Optical Data Storage

Scanning near-field optical microscopy.

An average human eye can see details down to 0,07 mm in size. The ability to see smaller details of the matter is correlated with the development of the science and the comprehension of the nature. Today's science needs eyes for the nano-world. Examples are easily found in biology and medical sciences. There is a great need to determine shape, size, chemical composition, molecular structure and...
