Overall Design of Miniature Spectrometer Based on Android
A spectrometer based on the Android processing system instead of the traditional personal computer system is developed in order to overcome the inconvenience in outdoor using and satisfy the needs of miniaturization and portability. The design of the optical system, mechanical structure, electronics and application program (APP) is introduced. To simplify the structure of the optical system, a plane holographic concave grating is used in the system, and the 3D printing technology is used to shape the mechanical structure. With a linear CCD array (TCD1304DG) as the photoelectric detector and an STC15 microcontroller unit (MCU) as the core, a high resolution spectrum data acquisition system based on the Android system is designed with Android USB (universal serial bus) communication. APP is developed for real-time processing of spectral data. The electronic shutter technology is utilized to realize the real-time adjustment of CCD integral time and satisfy the requirement on the portable spectrometer working in different environmental conditions. The design scheme uses the Android system as the data processing platform instead of the traditional personal computer system, exhibiting portability advantage.
