A detection device and a detection method are disclosed in the embodiments. The detection device comprises a light source, a first image information acquisition unit, a first charge coupled device (CCD), a first light splitter, and a first analyzer. The first image information acquisition unit is configured to receive a first light signal from the light source and transmit the first light signal onto a substrate, and to acquire a first image light signal generated by transmitting the first light signal onto both an edge of a first ID figure on the substrate and an edge of the substrate, and transmit the first image light signal to the first light splitter; the first light splitter is configured to transmit the first image light signal to the first CCD so that the first CCD outputs a first electrical signal; and the first analyzer is configured to receive the first electrical signal outputted from the first CCD and analyze wave crests of the first electrical signal, thereby obtaining a distance between the edge of the first ID figure on the substrate and the edge of the substrate. The detection part and detection method are used for substrate detection.
