The project as the 973 program will carry out original basic researches direct at fast optical imaging techniques with nanometer resolution. It is to come up with new optical information acquisition methods beyond the diffraction limit, and to develop independent innovation technologies of dynamic, nondestructive optical detection and imaging for life science. Meanwhile, it is aimed to solve key technical questions in nanometer-resolution optical imaging devices and systems, and to lead the development of China’s high-end optical imaging instrument technologies. The Project directed by Prof. Liu Xu in Dept. of Optical Engineering is designed to support China's long-term planning and development of nanotechnology and biotechnology fields, and to provide scientific basis for solutions of far field fast optical imaging with nanometer resolution.
