Ultra-fast optical space-to-time-to-space conversion technique among image signals and time sequential ones

摘要

Increasing demands for multi-media information in a networked society requires an optical fibre communication system with ultra-high transmission capacity at all times. A lot of researchers make strong effort to increase transmission capacity in an optical fibre communication system. The main target in multi-media is certainly ultra-high speed information processing including high-resolutional image signals transmission. Especially, to realize ultra-high speed image processing with a current communication infrastructure, it is necessary to develop and a new technique for ultra-fast conversion between image signals and time sequential ones. The novel optical ultra-fast space-to-time-to-space conversion technique among image signals and time sequential ones with an ultrarfast pulse laser is proposed. The proposed technique consists of combined uses of the concepts of time -space conversion, the time-frequency transform, and their inverses.
