摘要： Various surface and structural defects are currently inspected visually. This method is labor intensive, requiring large maintenance man hours, and is prone to errors. To streamline this process, herein is described an automated inspection system and apparatus based on several optical technologies that drastically reduces inspection time, provides accurate detection of defects, and provides a digital map of the location of defects. The technology uses a sensor that includes a pattern projection generator for generating a pattern image on the structural surface and a camera for detecting the pattern image generated by the pattern projection generator on the structural surface. Furthermore, the technology utilizes an image processing and correction apparatus for performing a pattern image and structural surface defect map correction and generate a distortion corrected defect map for a surface scan area on the structure that is incident on the sensor.

摘要： Additive manufacturing, such as laser sintering or melting of additive layers, can produce parts rapidly at small volume and in a factory setting. To ensure the additive manufactured parts are of high quality, a real-time non-destructive evaluation (NDE) technique is required to detect defects while they are being manufactured. The present invention describes an in-situ (real-time) inspection unit that can be added to an existing additive manufacturing (AM) tool, such as an FDM (fused deposition modeling) machine, or a direct metal laser sintering (DMLS) machine, providing real-time information about the part quality, and detecting flaws as they occur. The information provided by this unit is used to a) qualify the part as it is being made, and b) to provide feedback to the AM tool for correction, or to stop the process if the part will not meet the quality, thus saving time, energy and reduce material loss.

To streamline this process, herein is described an automated inspection system and apparatus based on several optical technologies that drastically reduces inspection time, provides accurate detection of defects, and provides a digital map of the location of defects. The technology uses multiple sensing/imaging modalities such as ring illumination angular scanning, coherent speckle scanning, multi-spectral imaging such as ultraviolet (UV), visible and infrared (IR) spectrums, and polarization detection.

摘要： A document processing device includes a controller and a sensor arrangement. The sensor arrangement illuminates a surface of documents. The gradient index lens array collects light reflected from the documents and transmits at least a portion of the collected reflected light onto a photodetector array. The photodetector array generates one or more electrical signals in response to a gradient index lens transmitting light thereon. The controller derives data including image data from the one or more electrical signals. The image data is reproducible as a visually readable image of the surface of the documents. The visually readable image has a resolution such that alphanumeric characters can be extracted from the visually readable image in response to the document remaining within a depth of field of the gradient index lens array while being transported via the transport mechanism. The depth of field is at least about 0.03 inches.
