The use of noncontact laser gauging systems for online measurement

John Peoples, Larry B. Weinstein

Increased worldwide competition has driven industry to find ever faster and more accurate techniques for product inspection. Although developed only recently, noncontact…

Online focus control sensor for laser welding offers improved reliability without process intrusion

Duncan P. Hand, Chris Peters, Julian Jones

A robust and non‐intrusive focus control system for laser welding has been developed under a collaboration between GSI Lumonics (Rugby) and Heriot‐Watt University in…

Achieving greater efficiency in NDT inspections

James Quirk

Describes the application of an ultrasonic sensing system for the non‐destructive inspection of welds as an alternative to X‐rays. Replacing radiography with ultrasound…

Advancements in infra‐red array detectors

Gareth J. Monkman

Despite many advances during the last decade in both infra‐red sensor and solid state camera technology, until now little headway has been made in the production of…

Application of SpectraScan tunable diode laser instruments to fugitive emissions

M.B. Frish, L.J. Edwards, P.N. McDonnell, J.M. Melnyk

The advantages of lasers over broad‐band light sources for spectroscopic measurements have long been recognized. Laser techniques offer the ability to measure the…

Scannerless laser range camera

Wilfried Schroeder, Ernst Forgber, Stéphane Estable

The requirement to quickly obtain 3D measurements is common to a variety of tasks in different fields of applications, i.e. robotics, space craft rendezvous and docking…

A strategy for accurate guidance of a manipulator using laser interferometry‐based sensing technique

Bijan Shirinzadeh, Pek Loo Teoh, Chee Wei Foong, YongDong Liu

Laser interferometry‐based sensing (LIS) technique has been proposed and established recently to track and perform dynamic measurements on a moving end‐effector of a robot…

Conductive polymer‐carbon black composites‐based sensor arrays for use in an electronic nose

Beth C. Muñoz, Gregory Steinthal, Steven Sunshine

Polymer‐carbon black composites are a new class of chemical detecting sensors used in electronic noses. These composites are prepared by mixing carbon black and polymer in…
