A light collecting probe named Multi-colored Integrated Receiving Optics (MICRO) is experimentally examined to verify its performance. For these purposes, the time-series signals of MICRO probe is compared with those of electrostatic probe and light-guided probe by monitoring, for example, such as OH radical chemiluminescence, CH radical band and droplet Mie scattering. In addition, the experiment was conducted by using laminar premixed Bunsen flame, turbulent premixed Bunsen flame and premixed spray flame, respectively. It was confirmed that the performance of MICRO probe was very useful and convenient to obtain the chemiluminescence signals from local regions in turbulent premixed Bunsen flame and premixed spray flame.
