This invention relates generally to organized assemblies of carbon and non-carbon compounds and methods of making such organized structures. The system and method may track sound pitch across the audio signal. The second dielectric layer is formed on one surface of the first dielectric layer. The radiation detecting system comprises an optical fiber cable 20 adapted to emit light at a region where radiation is applied and transmitting the emitted light, photoelectric conversion means 32 connected to at least one end of the optical fiber cable 20, and processing means 38 detecting when radiation is applied in accordance with an output signal of the photoelectric conversion means 32.
