Calibration of Kelvin clamp Euler angles for absolute instrument orientation

A method is described for calibrating the Euler angles of a kinematic Kelvin clamp in order to absolutely calibrate the orientation of an instrument. This paper covers a method for calibrating all three Euler angles, with an emphasis on the rotation about the vertical axis. This method uses a fixture employing a theodolite with an autocollimating eyepiece and an autocollimating prism.

Development of Indigenous Instrument for Visual Inspection of Reactor Internals

Pre-commissioning and periodic in-service visual inspection of reactor vessel internals, of Prototype Fast Breeder Reactor (PFBR), is a mandatory regulatory requirement. An Indigenous Instrument (Periscope) is designed for this purpose. The instrument is accommodated within a tube of 400 mm outer diameter and has a length of 10 meters. The single tube contains viewing, illumination and the asso...

Rock Bolt Inspection by Means of RBT Instrument

In this paper we present a new digital ultrasonic instrument for nondestructive inspection of rock bolts using guided waves. The Rock Bolt Tester (RBT) instrument applies long-range ultrasound to investigate bolt’s status, especially its grouting condition. RBT features an application tailored ultrasound probe that transmits high-energy, low frequency (below 100kHz) guided waves and is capable ...

A New, Portable High-Resolution Gamma-Ray Instrument For Use In On-Site Safeguards Inspection

Portable, high-resolution gamma spectroscopy has long been a vital technique in routine safeguards accountancy. The high resolution enables the spectrum analysis to accurately determine the isotopic content of the sample. All currently deployed systems for this application are based on liquid-nitrogen cooled, high-purity germanium (HPGe) detectors, with the spectrum analysis performed on portab...

A pipe-profiling adapter for CCTV inspection cameras: development of a pipe-profiling instrument

The principle of the optical section has been used to develop a profiling attachment for CCTV pipe inspection cameras. A light source, placed in front of the camera, projects a ring of light onto the pipe wall, which is then viewed by the camera. Any distortion in the pipe wall will be made visible by the light ring. The CCTV image is digitized by an electronic frame grabber and the light ring ...
