Abstract: The borescope includes an insertion tube, a first image processor, a model store unit, a pose calculator, a second image processor, a navigation image calculator and a display. The insertion tube includes a detection head and at least one sensor for receiving signals in the insertion tube and generating sensed signals. The first image processor is for calculating a first image based on first image signals captured by the detection head. The second image processor is for adjusting the initial pose calculated by the pose calculator to a navigation pose until a difference between the first image and a second image calculated based on the navigation pose and a predetermined model falls in an allowable range. The navigation image calculator is for calculating a navigation image based on the navigation pose and the predetermined model. The display is for showing the navigation image.

Abstract: A system includes a light emitting unit, a front mirror, a rear mirror, an imaging unit and a processor. The light emitting unit is configured to emit a collimated light beam. The front mirror is configured to reflect part of the collimated light beam to produce and project a front focused ring of structured light to an object to obtain a front reflected ring of light, and configured to allow part of the collimated light beam to pass by. The rear mirror is positioned downstream of a light transmitting path of the front mirror. The rear mirror is configured to reflect at least part of the collimated light beam passing by the front mirror to produce and project a rear focused ring of the structured light to the object to obtain a rear reflected ring of light.

Abstract: A surface roughness measurement device that in one embodiment includes main and auxiliary emitting fibers, multiple collecting fibers, an optical housing, main and auxiliary reflective mirrors, and an external circuit. The optical housing includes the fibers and defines an aperture for optically contacting a surface of an object. The main reflective mirror is arranged in the optical housing, for reflecting light emitted from the main emitting fiber to a detecting point of the aperture and reflected light by the object to the collecting fibers. The auxiliary reflective mirror is arranged in the optical housing, for reflecting light emitted from the auxiliary emitting fiber to the detecting point. The external circuit is for generating a laser beam to the main and auxiliary emitting fibers, collecting the reflected light from the collecting fibers, and calculating the surface roughness of the object based on the collected reflected light.

Abstract: A system for inspection of a blade of a wind turbine in operation is provided. The system comprises a light projection unit, an imaging unit and a processing unit. The light projection unit generates and projects a light pattern towards a blade of a wind turbine in operation. The imaging unit captures a plurality of scanning light patterns on the blade of the wind turbine during rotation of the blade. The processing unit is configured to process the plurality of the captured d light patterns from the imaging unit for inspection of deflection of the blade. A method for inspection of a blade of a wind turbine in operation is also presented.
