Abstract
A super resolution bore imaging system is disclosed for imaging a cylindrical bore. The system includes a controller, a photodetector configuration having a known pixel geometry, and an imaging arrangement that images bore surface segments onto the photodetector. In one embodiment, the controller is configured to acquire respective combinable sets of raw bore segment image data using the pixels of the photodetector configuration positioned, relative to the bore segment, at respective imaging-Z coordinates which are separated along the bore axial direction by a subpixel shift. In some embodiments, the pixel geometry is configured to provide super resolution along the circumferential direction without a change in position along the circumferential direction between acquiring the respective sets of image data. The controller combines the sets of raw image data to form a super resolution image data for the bore segment.
