New technology for determining position with great precision

13.05.2008
A new technique for measuring light has been developed by Mid Sweden University in Sweden. The technique consists of a new type of position-sensitive detectors and of extremely small, compact, and cost-efficient spectrometers.

"These new position-sensitive detectors can be used to measure the position of an incident point of light on a surface. This is done with great precision and rapidity," says Henrik Andersson, a doctoral candidate in electronics.

Both one- and two-dimensional detectors have been developed. It has also been important to be able to use the new technology together with silicon technology, which is the present standard in the production of electronic circuits of various types.

Tiny, compact, and cost-efficient spectrometers have also been developed for use in the processing industry. A spectrometer is used to determine the wave length of light, what we humans see as colors.

"A highly compact wedge-shaped interferometer has been developed to split the light into its wave lengths. Using a position-sensitive detector to meter the light intensity makes it possible to construct an extremely compact and cost-effective spectrometer that involves a minimum of optics," says Henrik Andersson.

The title of the dissertation is Position Sensitive Detectors - Device Technology and Applications in Spectroscopy. The whole dissertation is available at www.miun.se/biblioteket

Im Focus: Self-healing coating made of corn starch makes small scratches disappear through heat

Due to the special arrangement of its molecules, a new coating made of corn starch is able to repair small scratches by itself through heat: The cross-linking via ring-shaped molecules makes the material mobile, so that it compensates for the scratches and these disappear again.

Superficial micro-scratches on the car body or on other high-gloss surfaces are harmless, but annoying. Especially in the luxury segment such surfaces are...

Im Focus: Stellar cartography

The Potsdam Echelle Polarimetric and Spectroscopic Instrument (PEPSI) at the Large Binocular Telescope (LBT) in Arizona released its first image of the surface magnetic field of another star. In a paper in the European journal Astronomy & Astrophysics, the PEPSI team presents a Zeeman- Doppler-Image of the surface of the magnetically active star II Pegasi.

A special technique allows astronomers to resolve the surfaces of faraway stars. Those are otherwise only seen as point sources, even in the largest telescopes...

Im Focus: Heading towards a tsunami of light

Researchers at Chalmers University of Technology and the University of Gothenburg, Sweden, have proposed a way to create a completely new source of radiation. Ultra-intense light pulses consist of the motion of a single wave and can be described as a tsunami of light. The strong wave can be used to study interactions between matter and light in a unique way. Their research is now published in the scientific journal Physical Review Letters.

"This source of radiation lets us look at reality through a new angle - it is like twisting a mirror and discovering something completely different," says...

Im Focus: Revealing the secret of the vacuum for the first time

New research group at the University of Jena combines theory and experiment to demonstrate for the first time certain physical processes in a quantum vacuum

For most people, a vacuum is an empty space. Quantum physics, on the other hand, assumes that even in this lowest-energy state, particles and antiparticles...
