Imaging systems allow the identification and quantification of objects in various media, with the application of different exposure and illumination methods.

Research emphasis is on physical and technical requirements for image acquisition, as well as on the integration of additional process parameters.

A wide range of camera and illumination technologies are available. Depending on the desired application, different technologies can be combined and equipped with auxiliary sensors. According to customer specifications development of purpose-built designs are also possible. These techniques can provide the quantification of gas- and oil leakages, as well as the identification of minute organisms in fine layers of the water column. Further fields of application include the automated ex-situ examination of object characteristics (e.g. counting of otolith year rings for age determination of fish), or continuous measurements of sediment particle transport in coastal areas or rivers, to provide information of changes in the land-water interface in combination with current measures. Comprehensive code-libraries for data evaluation allow high availability of processed data.

For measurements in contaminated areas or areas of difficult access our systems offer autonomous modi and network solutions that allow a remote operation. The deployment of these systems e.g. on Remotely Operated Vehicles (ROV´s) in the deep sea is therefore possible.

Research topics include:

• Optimisation of camera and illumination techniques
• Differentiation of dispersed particles in liquids
• Differentiation of objects by numeric characteristics, spatially resolved
• Combination with additional process parameters
• Automated measurements on autonomous systems
