The 2009 International Conference on Optical Instrument and Technology (OIT’09) is the second event following the OIT’08 and it is sponsored corporately by SPIE, CIS and COS. OIT’09 is a professional conference which takes instrument and related technology as its core. To promote the integration of science with technology in instrumentation fields, the conference is combined with the exhibition of “The 20th Fair for Measurement Instrumentation and Automation (MICONEX)”. It can be expected that OIT’09 will promote the continuous development of optoelectronic technology & instrument knowledge and stimulate new energy to the industry.

Scientific instrument is an indispensable branch and plays more and more important roles in developing national economy, also in the fields of scientific research. Optoelectronic instrument and technology is the essential component of scientific instrument. It has its outstanding functions in many technical spheres such as: detection; observation; information collection, transfer and storage; communication; economization on energy; environmental protection; inspection and prevention of food security, traffic safety and mine safety; measure and control for aviation and space engineering, etc.
