Online scanning detection device and cigarette blasting bead detection device

The invention provides an online scanning detection device and a cigarette blasting bead detection device, and the device comprises a detector assembly which comprises a detector; and a ray source assembly which comprises a ray source for emitting detection light. The detector and the ray source are oppositely arranged; a detection channel for a conveying line of a to-be-detected object to pass through is formed between the detector and the ray source; a first included angle theta is formed between the direction of detection light emitted by the ray source and the conveying direction of the conveying line; the first included angle is an acute angle, the detection light forms a diagonal plane on the to-be-detected object, a second included angle is formed between the diagonal plane and thecross section of the to-be-detected object, the second included angle and the first included angle are complementary angles, and the detector acquires the detection light to form an image for separating laminations in the to-
