Abstract
A novel spectrum measuring system, which was based on the embedded system of ARM, controlled by a PC was developed. The system is composed of a monochromator, a high-precision voltage amplifier, an ARM7 system and a PC. The monochromator convert optical signal into electronic signal, and the signal is then amplified by the voltage amplifier. Then the amplified signal is converted to digital signal by the ARM7 system. At the end, the digital is send to the PC by the USB interface. After the processing and analyzing of the data, PC can measure and display the spectrum of the light source real-time. The system can measure the spectrum and chromaticity coordinates of light source and display device with high precision, and has a friendly interface.
