Detection device, detection apparatus and detection method

A detection device, comprising:

• a detection assembly comprising at least two rows of optical detection devices, wherein the row of the optical detection devices are arranged along a first direction in a field of view on a surface of a to-be-detected object, and each row of optical detection devices comprises at least two optical detection devices, the optical detection devices in one row are arranged along a second direction in the field of view on the surface of the to-be-detected object, and each of the optical detection devices is configured to detect the to-be-detected object, where the second direction is perpendicular to the first direction;
• and
• a driving assembly configured to drive the to-be-detected object to move along at least one of the first direction and the second direction, or drive the detection assembly as a whole to move along at least one of the first direction and the second direction,
• wherein the driving assembly comprises a first driving component configured to drive the to-be-detected object to move along the first direction and the second direction with respect to the optical detection devices, wherein
• the first driving component, during operation, drives the to-be-detected object to reciprocate along the first direction, wherein a travel distance of one way in reciprocating is greater than or equal to one row spacing, and the row spacing indicates a distance between adjacent rows;
• and
• every time before the to-be-detected object is driven to change direction, the first driving component drives the to-be-detected object to move along the second direction with a predetermined distance, where the predetermined distance is greater than or equal to an interval between adjacent optical detection devices along the second direction.
