The phase jumps dynamics in a photosensitive Belousov- Zhabotinsky reaction has been studied. It was found that an initially inhomogeneous phase distribution evolved to a homogeneous one, so that the phase at phase-lag points rises to the value at phase-lead points. A steep phase distribution was shown to become smoother in the course of time, inducing a dephasing wave which restores the system to a uniform phase. Applications of photosensitive chemical reactions to image processing (image storage, inversing, contouring) are discussed. Acknowledgments. Many thanks to Drs. Vadim N. Biktashev and Mikhail R. Stepanov for helpful discussions of the subject; special acknowledgments to Professor Arthur T. Winfree who read the manuscript carefully and helped in its structure improvement. Introduction A number of processes in solid state physics, theory of lasers, chemistry and biology can be described in terms of the theory of coupled oscillators [1]. Autooscillating chemical reactions, su...
