Tracking frequency laser distance gauge

Review of Scientific Instruments, 2005
Advanced astronomical missions with greatly enhanced resolution and physics missions of unprecedented accuracy will require laser distance gauges of substantially improved performance. We describe a laser gauge, based on Pound–Drever–Hall locking, in which the optical frequency is adjusted to maintain an interferometer’s null condition.

Analysis of buckling in dual-gauge tracks

Proceedings of the Institution of Civil Engineers - Transport, 2008
Two types of track gauges are currently in use in the Spanish railway network: the traditional ‘iberian’ wide gauge of 1668 mm used in the conventional network and the international 1435 mm gauge used for the high-speed lines. The dual-gauge track, in which a third rail is added to the classical two-rail layout, has recently been proposed for the ...

Semiconductor laser tracking frequency distance gauge

SPIE Proceedings, 2009
Space-based astronomical instruments and gravitational experiments require dramatically improved distance measurement accuracy. The Tracking Frequency laser distance Gauge measures to picometer accuracy. We discuss the design of the semiconductor laser version and its controller.

Acoustic detection and tracking of a pipeline inspection gauge

Journal of Petroleum Science and Engineering, 2020
Abstract Pipeline Inspection Gauges (PIGs) are widely used for monitoring and managing pipeline integrity. During a pigging operation it is fundamental to have a continuous measurement of the PIG position and movement, in order to achieve the best inspection and to have an early warning in the case the device is stuck.

Gauging software readiness with defect tracking

IEEE Software, 1997
In the competitive commercial software market, companies feel compelled to release software the moment it is ready. Their task is treacherous, treading the line between releasing poor quality software early and high quality software late, Finding a sound answer to the question: "is the software good enough to release now?" can be critical to a company ...

Assessment of the planned position of the track gauge of existing railways

Innotrans, 2022
The article considers the assessment of the influence of geometry of rail threads in terms of actual values of the lateral pressure coefficient from the impact of transverse forces during the passage of railway rolling stock.
