ABSTRACT:
An image data acquisition system for acquiring visible spectrum image data used in the inspection of circuit boards. The system comprises a rigid structure having upper and lower banks of cameras and telecentric lenses mounted in axial pairs at a substantially right angle to the circuit boards which are transported on the conveyor below. The cameras have overlapping fields of view which form a directionally contiguous band or two-dimensional web of sensor coverage. A beam splitter and mirror arrangement is mounted to the structure under the upper and lower banks such that light striking the mirror is reflected into the lower bank of cameras while light striking the beam splitter is partially reflected toward the mirror and partially transmitted through the body of the beam splitter into the upper bank of cameras.
