 +**Seminar:** Self-Mixing Interferometry: a Universal Yardstick to Measure Almost Everything
 +**Speaker: Prof. Silvano Donati**, University of Pavia, Department of Electronics, Faculty of Engineering, Italy
 +
 +**Location:** The University of Queensland
 +
 +**Abstract:** In this talk, we start with a theoretical introduction to mutual- and self-coupling phenomena in laser oscillator, and then describe in details the principle of operation of self-mixing interferometer, a new coherent configuration for the measurement of dimensional and kinematic quantities such as: displacement, distance, vibration amplitude, thickness, and angle, and also physical quantities like: coupling factors, line width, alfa-facto index of refraction. In the measurement arrangement, the laser undergoes self-injection at weak level, leading to an amplitude and frequency modulation driven by external optical path length. Then we will describe the developments of a displacement-measuring instrument, first by using the up/down counting of mode hops, then extending the principle of measurement to the case of a diffuse target, reflecting back a field affected by the speckle-pattern statistics. Third, we will report on the successful implementation of two-channel (or, referenced) vibrometer, based on analogue processing of the self-mix signal, in which the speckle-related amplitude errors are removed thanks to a servo-loop concept, and the instrument is capable of true differential operation, on diffuse surface, like a normal optical interferometer operates on legs ending with reflective surfaces. A survey of performances achieved in different design will conclude the talk.

His H factor is 23.
 +
 +He was the founder (1996) and the past Chairman (1997-01) of the Italian LEOS Chapter. Has been LEOS Vice President Region 8 Membership (2002-04), LEOS Board of Governors Elected Member (2004-06), Treasurers of the Italian LEOS Chapter (2002-06), Counselor of the IEEE Student Branch in Pavia (2001-07) and LEOS Distinguished Lecturer. Member of the NT Council Fellow Board, Memne=ber of OSA International Advisory Council.
 +
 +In 2005 he championed the merging of the two North and Central-South Sections in one Italy Section. Then he has been ViceChair in 2006/07 and is presently Chair of the Italy Section for the term 2008/09.
 +
 +He has been Visiting Professor in University of New Mexico (1992), National University of Taiwan (2005), Universita Catolica del Peru (2006) and National Sun Yat Sen University (2007, 2008).
 +
 +He has been the Guest Editor of several Special Issues, on Fiber Optics and Passive Components (JSTQE Sept. 1999), on Laser Interferometry (IoP Journal of Optics A 1998 and 2002, SPIE Optical Engineeing. 2001) of a Feature Issue of IEEE Journal Quantum Electronics, Sept. 2002, on Optical Chaos and Applications to Cryptography and of one on Photodetectors (2004).

 +**Seminar:** Simulation of High-Fidelity Radar Environments for RWR testing
 +
 +**Speaker: John Chester-Parsons**, EM Simulation Technology
 +
 +**Location:** Queensland University of Technology
 +
 +**Abstract:** Modern military platforms come under increasing threat in the new battle space, with ever increasing workload on the crew more emphasis is being placed on the platform's Defensive Aid System (DAS) to alert crew to potential threats. This presentation looks at the broad range of threats, DAS and in particular how Radar Warning Receivers need to be tested using sophisticated simulation equipment.
 +
 +**Speaker Biography:** John Chester-Parsons BSc (Hons) C-Eng F-IET M-IoD John is currently Managing Director of EW Simulation Technology in Farnborough UK and Special Interest Group leader of the EO/IR group in the UK MoD EW Tower of Excellence. Before joining EWsT he was MD and Technical Director of ESL Defense, after leaving Thales Optronics (Bury st Edmunds) where he was Business Development Manager for Countermeasure Dispensing Systems. Prior to working at Thales he was R&D manager at Wallop Defence Systems, working on advanced pyrotechnic flares and rockets. He joined Wallop from Philips Infrared Sensors (now part of Selex) where he spent 17 years developing advanced IR focal plane arrays.
 +
 +John is a chartered engineer, a fellow of the IET and a member of the Institute of Directors. Apart from enjoying family life he relaxes with theoretical cosmology and active astronomy.
