1Novel fiber-optical interferometer with miniaturized probe for in-hole measurements显示文摘Today, micro-system technology and the development of new MEMS (Micro-Electro-Mechanical Systems) are emerging rapidly. In order for this development to become a success in the long run, measurement systems have to ensure product quality. Most often, MEMS have to be tested by means of functionality or destructive tests. One reason for this is that there are no suitable systems or sensing probes available which can be used for the measurement of quasi inaccessible features like small holes or cavities. We present a measurement system that could be used for these kinds of measurements. The system combines a fiber optical, miniaturized sensing probe with low-coherence interferometry, so that absolute distance measurements with nanometer accuracy are possible.Robert Schmitt Tilo Pfeifer Frank Depiereux Niels Knig 2008Optoelectronics Letters2008,4,2:3
2Interferometric measurement of injection nozzles using ultra-small fiber-optical probes显示文摘The measurement of boreholes with diameters smaller than 500 μm is a demanding task that cannot be performed using state-of-the-art production metrology. In this letter, a miniaturized fiber probe with a diameter of 80 μm is presented. A probe is used for low-coherence interferometry to conduct highly precise measurements of form deviations of small boreholes. Measurements conducted in nozzles are also presented. The results prove the potential of the fiber-optical sensor for quality inspection of high-precision parts, such as injection nozzles, for common-rail diesel engines.Tilo Pfeifer Robert Schmitt Niels Knig Guilherme Francisco Mallmann 2011Chinese Optics Letters2011,9,7:1

6Optimization of Multi-Criteria Experiments with Fuzzy Results显示文摘The classical design of experiments (DoE) method can optimize systems with one technical re- sponse and multiple inputs. The objective of this study is to optimize multiple technical responses at the same time by integrating fuzzy logic transformation into a DoE system. The transformation from technical responses to the individual fuzzy responses and the overall fuzzy response are first defined, and the fuzzy response system is established. The method used to optimize the overall fuzzy response is introduced and discussed. The results show that the established fuzzy response system can optimize systems with multiple technical responses and multiple inputs.杨帆 吴甦 Tilo Pfeifer Klaus Hense 2006Tsinghua Science and Technology2006,11,6:1
