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.

متن کاملDevelopment 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...
متن کاملRock 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 ...
