The sensor housing includes a plurality of light-emitted diode (LED) light sources, a plurality of cameras, and a plurality of optical devices. Each camera of the plurality of cameras is positioned within a respective horizontal layer of the plurality of horizontal layers and configured to detect a respective range of wavelengths of light. The plurality of optical devices is configured to receive light reflected by the surface through a common input lens and direct the light to one of the cameras of the plurality of cameras depending on a wavelength of the light. The controller is configured to receive signals from the plurality of cameras indicative of the light reflected by the surface and determine whether there is any foreign object debris material on the surface using the signals from the plurality of cameras.

    Abstract: A method and a system for scanning an elongate structure. A scan of the elongate structure with a fluid in a cavity of the elongate structure is received. The scan is generated by a scanner using an x-ray beam. Data in the scan is filtered to remove a portion of the data in the scan attributable to the fluid to form filtered data, enabling detecting an inconsistency on a wall of the elongate structure in the filtered data.

    Abstract: A method may include scanning a surface of a composite workpiece with multiple electromagnetic pulses, each of the multiple electromagnetic pulses being associated with a respective location on the surface of the composite workpiece. The method may further include, for each respective location on the surface of the composite workpiece, receiving a response to one of the multiple electromagnetic pulses at a multi-mode fiber, the response including multiple wavelength components, time shifting the multiple wavelength components with respect to each other by passing the response through the multi-mode fiber to produce a wavelength-binned pulse, sampling the wavelength-binned pulse at time intervals corresponding to the multiple wavelength components to determine a set of wavelength intensity levels corresponding to the multiple wavelength components, and identifying a type or condition of material at the respective location on the surface of the composite workpiece based on the set of wavelength intensity levels.

    Abstract: According to various examples, techniques for detecting an off specification void in an item produced by an additive manufacturing process are presented. The techniques can utilize a system that includes cameras positioned to capture images of deposition of material in an additive manufacturing receptacle from multiple angles. The system can include at least one hardware electronic feature detector hard coded to detect features of elements of the material in image data derived from images. The system can further includes at least one electronic processor configured to perform a method of receiving feature data from the at least one hardware electronic feature detector, generating an electronic three-dimensional representation of the material in the additive manufacturing receptacle from the feature data, determining from the electronic three-dimensional representation of the material in the additive manufacturing receptacle that an off specification void exists, and providing an alert.

    Abstract: An example system for inspecting railcar axles includes a flash source, an infrared camera, and a trigger sensor. The flash source is configured to apply a thermal pulse toward a surface of a railcar axle of a railcar wheelset, while the railcar wheelset is on a track. The infrared camera is configured to capture infrared data indicative of a thermal response of the surface of the railcar axle to the thermal pulse. The trigger sensor is configured to trigger the flash source to apply the thermal pulse based on a position of the railcar wheelset on the track. The example system can also include a processor configured to determine whether the captured infrared data is indicative of a crack on the surface of the railcar axle, and a vision camera configured to capture an image of the surface of the railcar axle.
