The challenge lies in how to distinguish and detect each group of microparticles when multiple groups of microparticles are present. [Solution] The microparticle swarm detection device 10 irradiates a predetermined area including the workpiece 60 with green sheet laser light and red sheet laser light, switching the emission timing of these lights in a time series, and uses the imaging unit 15 to capture a video of the predetermined area including the workpiece 60. Then, frames captured with green sheet laser light and frames captured with red sheet laser light are extracted from the captured video to generate a video of green frames and a video of red frames. Subsequently, the microparticle swarm detection device 10 detects microparticle swarms based on the extracted video of green frames. The microparticle swarm detection device 10 also detects microparticle swarms based on the extracted video of red frames.
