Research on miniature spectrometer system based on phone hotspot transmission

In order to meet the needs of miniaturization of the spectrum detection system and real-time on-site detection,a miniature spectrometer system based on mobile phone hotspot transmission and Android platform was developed.The system collects the spectral signal of the measured object through the spectrometer and records the spectral images through the CCD detector.The Open WRT module on the spectrometer end is used to connect and transmit the spectral image to the mobile phone which opens the hotspot.The phone uses the Android platform to process and graphically display the spectral image.The experimental results show that the miniature spectrometer can accurately obtain the spectral data of the target and display the spectral curve in real time on the mobile phone.The mobile phone hotspot method can achieve point-to-point long-distance and fast transmission.The miniaturization of the spectrometer and wireless transmission meet the needs of on-site testing and has practical application value.
