Easy integration of functional regions into optical components generated by 3D printing

With this process, 3D printed optical elements can be optimized. Functional properties such as diaphragms, color filters or achromats can be integrated into the design of optical components using microcavities equipped with functional substances. The process can be implemented cost-effectively and enables the simple and efficient integration of new materials.



Rapid Phenotyping of Seed Oil Content – Novel fully automated high-throughput sorting device

This system, already realized as prototype, is capable of analyzing the oil content or other parameters in individual seeds from a bulk of seeds as well as sorting the individual seeds based on their properties in a fully automated and high throughput process with a high accuracy.



COMPASS – Compact Multi-Pass Amplifier System: Leistungsstarker UKP-Laser-Verstärker (kW-Bereich)

This multi-pass amplifier concept offers a previously unequalled output power in the kW range with a compact design and various scaling and modification options.



Reliable quantification of the cw background of a pulsed laser: BIRD – Background-to-Impulse Ratio Detector

This measuring instrument is able to determine the continuous wave power share of the total power of a pulsed laser reliably. This information is very helpful for the development of pulsed lasers and also for monitoring pulsed lasers during operation. The unit can easily be integrated into existing systems.



Robust One-shot Short Coherence Interferometry ROSI

The "robust one-shot interferometry" (ROSI) developed at the University of Stuttgart has been optimized in several aspects and now offers a miniaturized, robust and long-term stable as well as high-precision point and line profile measurement at very high measurement and evaluation speeds. The system is particularly suitable for demanding applications such as inline inspection in industrial production.



Simultaneous determination of changes in resistance and temperature in bridge circuits

The new concept of evaluation for bridge circuits offers the possibility of simultaneous determination of the change in resistance and temperature without the use of additional temperature sensors.
An offset can be directly compensated, which pays off especially in areas, where high accuracy is required.



Optimierte Filter zur Erkennung von Bildmerkmalen z.B. bei der Oberflächeninspektion

With these customized filter banks, error classifications with significantly higher selectivity and better detection rates can be achieved. The method can be easily integrated as software into existing systems for surface inspection.



Non-contact, simultaneous acquisition of topography and spectral data of an object

By cleverly combining two conventional methods together with a feedback strategy for mutual improvement, topography and hyperspectral measurements can now be performed in parallel on three-dimensional objects for the first time.



Efficient and cost-effective in situ measurement of growth-related soil parameters

To obtain best quality and quantity results for plant growth in soils and substrates, knowledge of the water and ion content of the soil and thus the dosage of irrigation and fertilizer is fundamental. This is particularly true when we want to support sustainability and the preservation of resources, but also wish to increase yield.
At the Institute of Agricultural Engineering of the University of Hohenheim a technology has been developed that measures soil water content, suction tension and salt content simultaneously and on-site. Signal transmission and the evaluation can be performed telemetrically or via cable, on-site or remote. The technology uses laser diodes, no spectroscopy is required.



Refractive lenses of rolled and structured films for X-ray optical systems

The newly-invented X-ray lens allows the focusing of X-rays on a point focus of less than 10 µm diameter and also distinguishes itself through high transmissivity and low absorption losses. It is especially interesting for X-ray analysis processes for which a high radiation intensity is required since tenfold radiation intensities are achieved in the focus.
The lenses are easy to manufacture and thus cost-effective.



Permanent air layer under water reduces friction and prevents fouling & corrosion

Within a project of the Baden-Württemberg Stiftung a novel surface technology has been developed that can hold gas molecules between a surface and surrounding liquids. Such a material could be extremely useful in shipbuilding rendering toxic anti-fouling coatings obsolete and simultanously reducing frictional resistance between vessel and seawater, thus saving fuel.



VacuShut, a pressure dependent self-opening and -closing vacuum container for samples which are sensitive to the atmosphere

A novel device for handling samples sensitive to the atmosphere has been developed at the Karlsruhe Institute of Technology (KIT). It allows samples prepared under vacuum or inert gas atmosphere to be stored safely for introduction into the measurement chamber of an analytical instrument. A complex and expensive air-lock or manipulator is thus not required. The novel vacuum container is simple, cost-effective and reusable.



Phase-analog displacement sensor – Inexpensive and inductive, even contactless

The inductive sensor principle, which also works contactless, enables a phase-analogue and robust detection of paths or angles in all areas of industrial automation, automotive engineering, traffic engineering or medical technology. Large path lengths from a few centimeters up to many meters with analog resolution can preferably be measured.
