Taufiq Widjanarko is a Research Fellow at Manufacturing Metrology Team, Advanced Manufacturing Research Group, Faculty of Engineering, University of Nottingham. He currently works on the development of multi-sensor measurement technology for in-line process monitoring of laser power bed fusion (L-PBF) of metal powders in Additive Manufacturing (AM). Prior to current task he worked in a brief project on the simulation and design of an in-process texture measurement for conventional and additive manufacturing machining applications. The method combines optical scattering and machine learning techniques to implement a rapid in-line measurement process.
Before joining University of Nottingham he was a Research Engineer at the Engineering and Physical Science Research Council (EPSRC) Centre in Intelligent Automation, Wolfson School of Mechanical & Manufacturing Engineering, Loughborough University, UK from 2013-2016. His responsibilities are on the optical engineering and imaging aspects of the industrial automation research, in particular the integration of 3-D computer vision and optical measurement systems with the industrial robotic manipulator arms. From 2011-2013 he was a Research Associate at the EPSRC Centre for Innovative Manufacturing in Through-life Engineering Services, Cranfield University,UK where he worked on the development Non-Destructive Inspection (NDI) system for high-technology/complex engineering components inspection. The tasks included the development of an image processing/recognition algorithm for automatic surface/sub-surface defect identification of thermographic images, and the development of a semi-automatic (robot-based) system for fast non-destructive inspection of batch of engineering components.
Taufiq has experience both in industry as well as long background of research and education in optics and imaging. His experience in industry including his position as a field and commissioning engineer in the Fiber-In-The-Loop (FITL) project Alcatel Telecom Indonesia, Jakarta in 1997. He also briefly worked as a programmer (part-time) at Vehicle Occupancy Ltd, Leicestershire prior coming to Cranfield.
His long interests and research experience in optics and imaging started back as early as his undergraduate education in Engineering Physics (with minor in Applied Optics) at Institute of Technology Bandung (ITB), Bandung, Indonesia in 1995, where he developed a simple set-up and data processing algorithm for characterisation and performance assessment of the CCD system for astronomical photometry at Bosscha Observatory, Indonesia. Later as a Fulbright scholarship recipient, he pursued his MSc in Electro-Optics at University of Dayton, Ohio, US where he submitted a dissertation on image processing algorithm for extending depth of focus of a conventional optical microscope which was completed in 2000. The developed algorithm is to improve the existing focus variation method - a 3D reconstruction method widely employed in surface metrology. After two research stints also in States in the investigation of optical scanning holography for data encryption at Virginia Tech, Blacksburg and reinforcement learning for target recognition at University of Memphis, Tennessee, he subsequently came to UK to carry out research on the development of a broadband optical interferometry system for high precision measurement of surface and sub-surface features in a single-shot acquisition which was completed in2011. The developed prototype, Hyper-Spectral Interferometry (HSI), has received a UK and international patent and recognition from the Royal Society.
He read optical engineering for his doctorate research under supervision of Prof. Jonathan Huntley at Loughborough, UK.
