讲座题目 : Tomography as Sensor Fusion
报告简介：Work with sensors and sensor fusion are increasingly seen as a high-volume measurement task of the future, most notably within the Internet of Things framework and as one of the main sources for Big Data. This inspires a fresh look at measurements, data and information processing paradigms to uncover the alignment of established concepts with emerging trends. One possible target is tomography, which is traditionally seen as applying an inverse problem solution to a set of carefully chosen measurements but also qualifies as a sensor fusion approach.
Tomography will be introduced briefly with emphasis on how the sensor head design works in relation with the measurement data inversion. This will be exemplified with some typical applications of hard-field tomography, posing the challenges of measurement access, as well as of required temporal and spatial resolution: imaging of gaseous fuel, THz tomography and Guided-Path Tomography for deformation imaging.
It will be argued that the typical perception of fusion as post-measurement merging of data and/or information can be widened to include the tomography sensing and imaging of a unique well-behaved function, which can be used directly, e.g. for classification decisions, since it embodies the combined effect of the targeted parameters. Such functions can be used also to disentangle secondary contrasts or calculating secondary quantities with subsequent model fusion. Furthermore, several such functions are still amenable to fusion in the traditional sense.
Krikor B. Ozanyan教授简介：Krikor B. Ozanyan (Mac in Engineering Physics; PhD in Solid-State Physics) has a 35 years’ career dedicated to photonics. After several posts as researcher and academic, incl. a NTNF Fellowship held at NTH Trondheim, he joined in 1998 the School of Electrical and Electronic Engineering at The University of Manchester (until 2004 Department in UMIST), where he is currently Professor of Photonics Sensors and Systems. Since 2010 he is Head of the Sensors, Imaging and Signal Processing research group. His main interests are in photonic materials, devices, systems and their application across the near UV, visible, infrared and THz spectrum. Among his achievements is the shortest wavelength ZnS/CdZnS heterostructure laser (1995), the first surface-phase diagram of INP (1997), as well as the pioneering of Guided Path Tomography (2005). He was appointed by the IEEE Sensors Council as Distinguished Lecturer of IEEE in 2008-2011 and has delivered worldwide in that period 20 invited lectures in Sensing and Tomography. He was the recipient of the technical award at the 2013 World Congress of Industrial Process Tomography, for his presentation of a new imaging system for Photonic Guided-Path Tomography. He has edited several Special Issues on sensor topics and is currently the Editor-in-Chief of the IEEE Sensors Journal.
Krikor is Fellow of the Institute of Engineering and Technology, Fellow of the Institute of Physics and Senior Member of the Institute of Electrical and Electronic Engineers. He is also Fellow of the Higher Education Academy and registered practitioner.
