Molecular image-processing devices based on chemical reaction systrems. 3: Some operational characteristics of excitable light-sensitive media used for image processing



Operational features of excitable Belousov–Zhabotinsky-type light-sensitive media that can be used to implement image-processing operations are discussed. They embrace (i) the main primitive responses of such media to light excitation as a function of medium acidity, temperature and light exposure, (ii) the characteristics of temporal evolution of stored media and (iii) the resolution and information content inherent in images stored by excitable media. It is shown that controlling the acidity of the medium, its temperature and the duration of light exposure enables one to get reproducible results.
