A bore imaging system comprises a photodetector configuration and a first bore surface imaging arrangement configured to transmit image light arising from a first image zone on a bore surface to the photodetector. The photodetector configuration comprises a first curved photodetector arrangement which is curved in a plane that is oriented transverse to an axial direction of the bore. The first curved photodetector arrangement comprises a first imaging array that receives image light along a direction transverse to the axial direction.

An inspection system for a heat exchanger having a vision system to obtain an image of an inner surface of the at least one tube.

A digital inspection assistant and a system and a method of using the inspection assistant as an aid during a visual inspection of a gas turbine engine are provided. In one aspect, the inspection assistant receives data that includes images captured by an optical probe installed through an access port of a gas turbine engine. The images can be still images or video of the interior of a core of the engine. A gateway can route the data to the inspection assistant. The inspection assistant can provide interactive inspection guidance to an operator and can detect component defects. The inspection assistant can provide real time defect analysis to the operator by generating an alert upon detection of a defect. The generated alert can be audible, a visual graphic presented on a display of the visual inspection, and/or some other suitable alert. The analysis results can assist the operator during inspection.

A front side of the box body is provided with a front mounting groove, a back side of the box body is provided with a back mounting groove, a waterproof keyboard and a control terminal are installed in the front mounting groove, a counter and a hard cable coil are installed in the back mounting groove, one end of the hard cable coil is connected with the control terminal, the other end of the hard cable coil is connected with a high-definition camera, the front side of the box body is rotatably connected with a front cover, the back side of the box body is connected with a back cover, and the box body is rotatably connected with the bracket through a strong resistance rotating shaft.

A mount assembly includes a stage including a base and one or more sidewalls extending upward from the base to define an elongated channel, and a holder including an elongated body having a first end portion and a second end portion opposite the first end portion, a bracket extending upward from the elongated body at the first end portion, and a foot extending upward from the elongated body at the second end portion. The elongated body is positionable within the elongated channel. An inspection device is extendable between the bracket and the foot.

Systems and methods for inspecting or maintaining a structure, such as a utility pole or a metal tower), with an unmanned aerial vehicle (UAV) are disclosed. The UAV can be configured to fly to a target location on the structure and measure characteristics of the structure such as a component thickness. The UAV can precisely repeat the measurement at a later time to determine any change in component thickness.

A probe driver may include a coupling that interfaces with a conduit section at a first position of the conduit section. A probe driver may also have one or more positioning elements to reposition the conduit section to interface with the coupling at a second position of conduit section in response to one or more commands based on a recorded inspection, where through completing the one or more commands is configured to initiate a second inspection identical to the recorded inspection.

An optical fiber laser induced breakdown spectroscopy detection device and a detection method are provided. The device comprises an optical fiber LIBS detector and a master control detection system. The master control detection system is installed in the master control room of a nuclear power plant, and the optical fiber LIBS detector is configured to perform detection in a pipeline. The master control detection system and the optical fiber LIBS detector are connected to each other via the transmission optical fiber and the control signal line. The remote on-line detection of the positioning and fixed point of the designated area of the inner wall of the main pipeline of the nuclear power plant can be detected on line in the master control room of the nuclear power plant.

Systems and methods for robotic inspection of above-ground pipelines are disclosed. Embodiments may include a robotic crawler having a plurality of motors that are individually controllable for improved positioning on the pipeline to facilitate image acquisition. Embodiments may also include mounting systems to house and carry imaging equipment configured to capture image data simultaneously from a plurality of angles. Such mounting systems may be adjustable to account for different sizes of pipes (e.g., 2-40+ inches), and may be configured to account for traversing various pipe support structures. Still further, mounting systems may include quick-release members to allow for removal and re-mounting of imaging equipment when traversing support structures. In other aspects, embodiments may be directed toward control systems for the robotic crawler which assist in the navigation and image capture capabilities of the crawler.
