In measurement of ultrafast phenomena caused by several photochemical reactions, multiple transitional spectral patterns contained in a signal pulse are directly associated with different interactions, allowing us to identify individual interactions from these patterns. We propose a new method by which we can detect multiple transitional spectral patterns contained in a signal pulse in parallel using optical spectrogram scope (OSS). In the experimental demonstration, we used an arrayed filter composed of matched filters recording three kinds of transitional spectral patterns in the OSS system, and we directly detected two different patterns contained in a signal pulse in parallel.
