In a first for Â鶹ֱ²¥ of Technology\u2019s forensics team, the ABC program “Can we help You” will use Curtin\u2019s innovative research into forensic techniques that expose forgery to illustrate some of the advantages of using the Australian Synchrotron facility in Melbourne.<\/p>\n

The program will demonstrate how a carelessly written cheque can be forged and then exposed as a forgery by examining it with a Synchrotron generated infrared beam.<\/p>\n

Professor Bill van Bronswijk explained the process.<\/p>\n

\u201cA synchrotron is a machine that accelerates electrons to almost the speed of light and as the electrons are deflected through magnetic fields they create extremely bright light\u00a0\u00a0 The light is channelled down beamlines to experimental workstations where it is used for research,\u201d Professor van Bronswijk said.<\/p>\n

Synchrotron light is unique in its brilliance and narrow focus, and can be generated across the range of the electromagnetic spectrum: from infrared to x-rays.\u00a0 This gives it a distinct advantage over conventional light sources for applications ranging from finding poison traces after an unexplained murder, characterising inks and pigments in documents and artworks, distinguishing characteristics of automotive paint pigments in hit-and-run car accidents to detecting explosives or illegal drugs on clothing.<\/p>\n

\u201cInfrared techniques are useful to identify inks and pigments in forgeries and counterfeit banknotes.\u00a0 The demonstration will use a cheque, made out to myself for \u2018seven thousand dollars only\u2019.\u00a0 Using a different ink, a \u2018one\u2019 was added before the \u2018seven\u2019 and the \u2018seven\u2019 became \u2018seventeen\u2019, thereby creating the forged cheque,\u201d Professor van Bronswijk said.<\/p>\n

\u201cWe should be able to see the difference in the inks and possibly even pick the part of the \u2018t\u2019 that was written over part of the \u2018n\u2019.\u201d<\/p>\n

Professor Roland de Marco, Dean Research and Development for Science and Engineering, outlined the advantages of Curtin\u2019s Australian Synchrotron foundation membership, held in conjunction with the Department of Industry and Resources (DOIR) and The University of WA (UWA) and offering significant beam time.<\/p>\n

\u201cCurtin has utilised 120 hours across the four operational beamlines during the past year, which is part of their contractual agreement as one of the founding members,\u201d Professor de Marco said.<\/p>\n

\u201cOur undergraduate and postgraduate students as well as staff are able to take full advantage of the high brightness of the synchrotron to undertake unique experiments such as the high resolution imaging of bones and tissues, the analysis of forensic evidence such as hair on poisoned victims, and a monitoring of the maturation of human eggs adopted in in vitro fertilisation (IVF).\u00a0 The brightness of the beam is the key factor that enables success with these otherwise difficult and challenging experiments.\u201d<\/p>\n

The program \u201cCan we help You\u201d goes to air on the ABC at 6.30pm on Friday 25th July.<\/p>\n
