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.

Apparatus (1) for checking tyres, comprising: a support frame (2); a flange (3); and an acquisition system (4) of three-dimensional images of a surface of a tyre, the acquisition system being mounted on the support frame and comprising: a matrix camera (5), a linear laser source (7), and a reflecting surface (12) which intersects the propagation axis (9) of the linear laser beam and the optical axis (6) of the matrix camera (5), wherein a first angle (50) formed between a first section (14) and a second section (31) of the optical axis (6) mutually symmetrical with respect to a normal to the reflecting surface in the respective point of incidence to the reflecting surface, is obtuse, and wherein a second angle (51) formed between a first section (16) and a second section (32) of the propagation axis (9) mutually symmetrical with respect to a normal to the reflecting surface in the respective point of incidence to the reflecting surface, is obtuse.

An exemplary embodiment provides a camera probe having an elongated housing provided with an external wall made of heat-resistant material enclosing an internal space. The housing has a forward opening covered by a window of heat-resistant radiation-transparent material and a position within the internal space for mounting a camera positioned to receive radiation from the window. At least one cooling channel is provided within or adjacent to the external wall, at least over a part of the external wall exposed to elevated temperatures during use of the probe. At least one gas exit port is provided adjacent the window and is oriented to cause gas leaving the gas exit port to sweep over an external surface of the window to keep it cool and free of debris.

A non-destructive testing device includes a tubular housing including a proximal end and a distal end. A conduit section is arranged at the proximal end, and a bendable articulation section secured to the conduit section and arranged at the distal end. A plurality of actuation systems each includes a control cable extending along the tubular housing and arranged at a respective circumferential position within the bendable articulation section, and an actuator disposed at the proximal end of the tubular housing and secured to the control cable.

An inspection cable guide mechanism of the present disclosure includes a heat-resistant sheath having flexibility through which a cable is allowed to be inserted and cooling air is allowed to flow toward a tip through a gap between the cable and the heat-resistant sheath, a segment stacked body configured by stacking segments having heat resistance configured to cover the heat-resistant sheath in a centerline direction, and a plurality of wires disposed around the heat-resistant sheath and extending along a centerline, one segment of the segment stacked body is swingable with respect to two segments adjacent to the one segment about swing axes extending in a direction perpendicular to the centerline, the two swing axes becoming centers when the one segment swings with respect to the two segments are perpendicular to each other when viewed in the centerline direction, and one end of each wire is fixed to one of the segments in the segment stacked body.

Video inspection systems are disclosed. In one embodiment a video camera for use in a pipe inspection system includes a camera head including an outer housing, a camera module assembly including video and non-video sensors, a processing circuit, and a data link receiver.
