Portable wireless multi-channel spectrometer based on Android platform

This paper described the design of a portable spectrometer, which could accomplish the mission of dose-rate and energy spectra analysis. The spectrometer system achieved a man-machine conversation platform for energy spectra data recording and processing using wireless WIFI communication technology and Android operating system. Emphases were focused on the scheme, including measuring principles, hardware design and software design. The principles, functions and cruces of every unit were explained in detail. Finally, according to measuring result of energy spectrum detection and contrast experiment, the capability of the instrument was analyzed. This system had 64k channels. The resolution was 3.81%.
