Abstract: A complex testing system was designed for flame spectrum and image detection based on the standard flame and the discrete equipments, i.e.SR-5000 infrared spectrometer, AvaSpec-2048 UV spectrometer and high-speed color CCD telecamera. With the button panel and the operation software, any discrete equipment can be operator independently, or more equipment can be operated simultaneously and the UV infrared image data can be acquired synchronously. The indication of oscilloscope shows that the synchronization delay is shorter than 50ns. As a result, the flame spectrum of the whole waveband and the image corresponding to every flame spectrum data were obtained in the experiments.
