UPH Electrical Engineering student published a paper on checking document originality using laser in an international journal
Instead of using dynamic set-up with moving laser and moving sensor, Wiwi used a simple approach employing static laser and static matrix of sensors. A HeNe laser (courtesy of the Physics Lab of Electrical Engineering UPH) and a cheap microscope equipped with CCD were employed in the set-up along with mirror and image capture box. The result was already presented in The International Conference on Advances in Computing, Control, and Telecommunication Technologies 2010 and awarded the UPH?s Student Scientific Paper of the Year award for 2011.
Later on, Wiwi Samsul extended the work to see how well such simple and cheap set-up can withstand the spatial and angular misalignment. In this work, Wiwi intentionally induced spatial and angular disturbances and check how well the system still can authenticate the paper. The results show that regardless of its cheap and simple set-up, the system still can tolerate spatial shift of 0.154 mm and angular shift of 3.59 degree. This work was then published in a SCOPUS indexed journal of Springer, the Journal of Optics, Vol. 44, Issue 3, 2015 (http://dx.doi.org/10.1007/s12596-015-0250-0). ?Undergraduate student?s work published in international journal is exceptional?, said Dr. Henri Uranus, the supervisor.
After graduation, Wiwi pursued his Master degree and Ph.D. in Electrical and Computer Engineering from Duke University. He is currently researching on microwave energy harvesting for his Ph.D. work.
