Abstract: An engineered video inspection system for high speed video inspection includes an array of light emitting diodes including light emitting diodes for use in time delay integration (TDI) inspection of web materials. The light emitting diodes of the array are selectively controllable to accomplish sequential illumination and carefully controllable imaging of a specified section of a continuously moving specimen or specimens. LEDs with different wavelength light output, or multi-wavelength light LEDs are utilized of rapid and reliable inspection of surfaces with varying color or contour or detect characteristics. The system also includes an array of optional backlighting elements to aid in illumination of semi-opaque specimens to accomplish inspection thereof.
