The invention discloses a detection system. The detection device is used for detecting a to-be-detected target, and comprises: an optical device disposed on the to-be-detected target and used for receiving first reflected light and second reflected light reflected by the to-be-detected target; a visible light imaging device for receiving the first reflected light through the optical device so as to obtain the image of the to-be-detected target; and an OCT imaging device for outputting the detection light to the to-be-detected target through the optical device and receiving the second reflected light from the optical device so as to obtain parameters of the to-be-detected target. By arranging the optical device, the first reflected light emitted by the to-be-detected target is transmitted to the visible light imaging device, so that two-dimensional imaging of the to-be-detected target is realized; and second reflected light emitted by the to-be-detected target is transmitted to the OCT imaging device, depth information of the to-be-detected target is obtained, and two-dimensional and three-dimensional scanning detection is achieved.
Description
technical field [0001] The present application relates to the field of circuit board detection, in particular to a detection system. Background technique [0002] In the detection of printed circuit boards, it is often necessary to detect the wiring, electronic components, and optical components on the circuit board, which usually requires computer vision systems to identify and detect them. In the prior art, industrial cameras and imaging lenses are usually used to take pictures of the circuit board to be tested, and then identify defects through the captured images, which can only provide two-dimensional information on the surface of the circuit board, but cannot determine the height information of the components on the board, the upper surface, etc. The internal defects of optical components are further inspected. Contents of the invention [0003] The present application provides a detection system, the detection device is used to detect the target to be detected, inc...
