IMAGING LIGHT AND COLOUR MEASURING SYSTEMS Techno Team Bildverarbeitung GmbH

APPLICATION OVERVIEW Imaging analysis of lighting scenarios and illuminated scenes are becoming more and more important. The complex analysis of various scenes requires the knowledge of the luminance distribution within the whole field of view or at least in many selected parts of it. Solving the necessary measuring tasks point by point either takes an enormous amount of time or is only possible within a coarse raster grid, if at all. Thus the development of spatially resolved radiation receivers has enabled the user to solve such measurement problems. Some of the most important measurement...

CALIBRATION PROCThe way to a calibrated ILMD/ICMD system For accurate data evaluation, all non-ideal properties of the system need to be corrected in relation to international agreed standards (e.g. luminance) typically using calibration factors. For this purpose, the software controlling the IxMD, needs a model and model parameters. The estimation of the model parameter is the aim of the individual adjustment of a measuring system. With the additional calibration the success of the adjustment will be checked and stated including the associated measurement uncertainty verified by...

SPECIFICATIONS The LMKG is at the center of the entire LMK product family with a photopic glass filter to adapt the system to the V(X)- function or a set of full filter glasses to realize the matching to the 2° CIE standard observer. It's robust construction, compact dimensions and lightweight means that it can be used in almost every environment and process for a wide range of light measurement tasks. In conjunction with our versatile software, a wide array of applications where imaging determination and evaluation of luminances can be addressed. A large selection of high-quality standard...

The characterization of different display types -small mobile phone displays up to large TV displays or also head-up displays - is an important topic in various R&D applications and the quality management for production accompanying processes. For example automotive displays and their very strict performance, quality, and safety requirements or the measurement of virtual displays (VR/AR, ocular systems) are becoming more and more critical. Imaging Luminance and Color measuring devices (ILMD/ICMD) can be used to analyse a various range of performance and quality benchmarks for the different...

Near Eye Display Measurement Imaging Luminance and Color Measuring Devices (ILMD / ICMD) in combination with adapted measuring lenses provide effective one-shot solutions to evaluate modern Near Eye Displays (NED). NED-suppliers asked for LMK-solutions adapted to their specific instrument structure. Here, the wide range of fields of view (FOV) and of NED-resolutions needs to be considered. On the basis of our experience in creating LMK's we offer a set of formulas to determine the basic parameters of lenses for different NED-concepts. We developed an optical system whose aperture-stop...

LMK POSITION VISION BASED ROBOTIC At the present time industrial robots produce a repeatability of 20-30 pm for positioning. Comparing the robotic-controlled LMK with a manually positioned luminance measuring device the former has considerably better reproducibility. An outstanding feature is the possibility of referencing the measurement positions with the use of the mounted LMK camera system. The software for the LMK POSITION can handle and transform both, the coordinate systems of the used optics for the LMK and the applied coordinate system for the device under test (DUT).Thus the...
