Following the success of IEEE Workshops on Imaging Systems and Techniques, Stresa, Italy in 2004, Niagara Falls, Canada in 2005, Minori, Italy in 2006, Krakow, Poland in 2007, and Chania, Crete, Greece in 2008, the 2009 IEEE Workshop on Imaging Systems and Techniques (IST 2009) will take place in Shenzhen, China, in collaboration with the Graduate School at Shenzhen of Tsinghua University (Tsinghua Shenzhen) and Chinese Instrumentation and Control Society. IST2009 deals with the design, development, evaluation and applications of imaging systems, instrumentation, and measuring techniques, to enhance detection and image quality. Applications for aerospace, medicine and biology, molecular imaging, metrology, ladar and lidars, radars, homeland security, and industrial imaging with emphasis on industrial tomography, corrosion imaging, and non-destructive evaluation (NDE) will be covered. The following areas will be particularly considered: ·Detectors and image formation ·Imaging system design, instrumentation and measuring techniques ·Compact design of optical system ·Linear and nonlinear techniques for image processing ·Biometrics ·Emerging technologies In addition, invited keynotes and special sessions will be arranged. It is planned to organise a special issue with a journal after the Workshop.
