Claim 0:
1. A device detection method for detecting a target device, comprising:
acquiring one or more first spectral intensity graphs for one or more predetermined regions in a cavity of the target device;
acquiring one or more second spectral intensity graphs for the one or more predetermined regions when the target device has finished N processing tasks, where N is a natural number; and
detecting a cleanliness in the cavity of the target device according to the one or more first spectral intensity graphs and the one or more second spectral intensity graphs,
wherein acquiring the one or more second spectral intensity graphs for the one or more predetermined regions comprises:
emitting an emission light emitted by a light source to each one of the one or more predetermined regions in the cavity of the target device;
receiving a refracted light refracted by the emission light from each one of the one or more predetermined regions; and
obtaining a second spectral intensity graph for each one of the one or more predetermined regions according to the refracted light,

wherein detecting the cleanliness in the cavity of the target device according to the one or more first spectral intensity graphs and the one or more second spectral intensity graphs comprises:
analyzing a first spectral intensity graph and a second spectral intensity graph for each one of the one or more predetermined regions; and
issuing an abnormal cleanliness prompt for a predetermined region of the one or more predetermined regions for which the first spectral intensity graph and the second spectral intensity graph are different when the first spectral intensity graph and the second spectral intensity graph for the predetermined region are different,

wherein the method further comprises:
performing a sensitivity detection on the emission light emitted by the light source when the first spectral intensity graph and the second spectral intensity graph for each one of the one or more predetermined regions are different.
