A lot of applications as well as in the laboratory range and industrial range need a short-wave infrared imaging system. Especially multispectral imaging in that wavelength region are often enable new applications for quality assurance and monitoring of industrial processes. Due to the cost of the SWIR image sensors a multispectral imaging system should be flexible and adjustable to realize a maximum of applications. Normally push broom devices will fulfill these requirements. Disadvantages are that the sample must be moved, the spectral crosstalk and the blurring between the different channels can disturb the processing, and the correctness of spatial resolution along the scanning direction lead to uncertainties for dimensional measurements. For that reasons a twelve-channel filter-based imaging system was designed. A motor driven filter-wheel with a high precision drive will ensure that the filters will be placed in front of a SWIR Image sensor very precisely. To compensate the spectral aberrations along the optical axis a second drive positioning the image sensor into the focus plane. This enable sharp images in all spectral channels as well as high SNR (depends also on the capability of the SWIR Sensor). Furthermore, this implementation allows also to focus without changing the adjustment of the objective lens. A special designed dome light using halogen bulbs delivers very homogeneous radiation on the sample table. For the image readout, the control of the drives as well as the image presentation a software with a graphical user interface was developed. To export the image stacks in 3rd party software the imaging software saves the multispectral images in the envi-format.
The aim of this work is to develop possibilities of an effective audit procedure shall be worked out. Audits are systematic, independent and documented processes for obtaining evidence. This ensures conformity with the requirements. In order to achieve certification according to standards, an external system audit must be carried out by an accredited company. These are very time-consuming and costly because the auditor has to be on site. A concept of how the audit can be carried out without an on-site appointment is developed and evaluated. The possibilities of current technologies - such as VR - are also considered and integrated into the concept. Due to the high-level structure this can be carried out on an integrated audit which combines different management systems.
New and revised standards are increasing the demands placed on management systems. The aim of this paper is to investigate how the effort required to create and maintain management systems can be minimized. A concept is presented, which also considers the integration of different management systems. First the existing management systems are evaluated. Then the requirements from practice are determined. These are examined and evaluated. Based on both results it is determined which requirements an integrated management system must fulfil. On this basis, a practical concept of an integrated management system is developed. As well optimal interfaces are considered. This concept is transferred into a web-based application. In order to ensure an optimal implementation and expandability, the structure is realized modularly.
