Claim 5:
6. A device detection system, comprising:
a spectrometer, configured to form one or more second spectral intensity graphs for one or more predetermined regions in a cavity of a target device when the target device has finished N processing tasks, where N is a natural number;
a light source, electrically connected to the spectrometer, for emitting an emission light;
a lens system, electrically connected to the light source and configured to refract the emission light emitted by the light source to each one of the one or more predetermined regions;
an optical signal receiver, electrically connected to the spectrometer, and configured to receive a refracted light refracted by the emission light from each one of the one or more predetermined regions and transmit an optical signal of the refracted light to the spectrometer;
an analysis device, electrically connected to the spectrometer and configured to receive one or more first spectral intensity graphs and the one or more second spectral intensity graphs for the one or more predetermined regions in the cavity of the target device, and detect 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; and
an abnormal prompt structure, located in the analysis device, and configured to issue an abnormal voice prompt or an abnormal text prompt when a first spectral intensity graph and a second spectral intensity graph for a predetermined region of the one or more predetermined regions are different,
wherein the analysis device is further configured to perform 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.
