    Abstract: A system and method is disclosed for detecting defects in the surface of a workpiece such as a fiberglass or composite part. A light source is positioned to direct light at the workpiece at an oblique angle with respect to the surface of the workpiece. At least one camera is positioned to detect light reflected from the workpiece and to generate a light signal corresponding to the reflected light. A polarizing lens is positioned between each of the at least one cameras and the workpiece. A processor is coupled to each of the at least one cameras to receive the corresponding light signals. The processor is programmed to process the light signals to detect any defects in the surface of the workpiece based on relative magnitudes of the received light signal. A video display and a printer are preferably coupled to the processor to show any detected defects.

    Abstract: An example system for inspecting a surface includes a laser, an optical system, a gated camera, and a control system. The laser is configured to emit pulses of light, with respective wavelengths of the pulses of light varying over time. The optical system includes at least one optical element, and is configured to direct light emitted by the laser to points along a scan line one point at a time. The gated camera is configured to record a fluorescent response of the surface from light having each wavelength of a plurality of wavelengths at each point along the scan line. The control system is configured to control the gated camera such that an aperture of the gated camera is open during fluorescence of the surface but closed during exposure of the surface to light emitted by the laser.

    Abstract: An example laser system includes a laser, a plurality of pulse stretchers coupled together in series, a feedback module, and a lens assembly. The plurality of pulse stretchers is configured to stretch pulse widths of laser pulses provided by the laser and to output stretched laser pulses. The feedback module includes a pulse delay comparator that is configured to compare a first laser pulse of the laser pulses to a corresponding first stretched laser pulse of the stretched laser pulses. The feedback module also includes a computing device that is configured to determine, based on a result of the comparing by the pulse delay comparator, an adjustment to a pulse stretcher of the plurality of pulse stretchers, and apply the adjustment to the pulse stretcher so as to modify a shape of a second stretched laser pulse of the stretched laser pulses.
