چکیده
Marc Rioux National Research Council, Canada Institute for Information Technology Visual Information Technology Ottawa, Canada, K1A 0R6 Abstract. We review some usual laser range finding techniques for industrial applications. After outlining the basic principles of triangulation and time of flight [pulsed, phase-shift and frequency modulated continuous wave (FMCW)], we discuss their respective fundamental limitations. Selected examples of traditional and new applications are also briefly presented. © 2001 Society of Photo-Optical Instrumentation Engineers. [DOI: 10.1117/1.1330700]

Precisely controllable broadband frequency sweeps using a semiconductor laser in an optoelectronic phase-lock loop
We demonstrate the generation of wideband frequency sweeps using a semiconductor laser in an optoelectronic phase-lock loop. The rate of the optical frequency sweep is locked to and determined by the frequency of a reference electronic signal, leading to an agile, high coherence sweptfrequency source for laser ranging and 3-D imaging applications. Using a reference signal of constant frequency,...
متن کاملThe Use of Aptamer in Detection of Pathogenic Bacteria-
Detection, identification and measurement of microbial pathogens is critical for protecting public health. Although microbial culture-based tests and molecular techniques are currently the most commonly used, these techniques are time-consuming and require complex tools and experienced individuals. Consequently, it is costly to analyze these techniques. The emergence of the aptamer led to the e...
متن کاملExperimental Investigation of Asymmetry of Vortex Flow Over Single Delta Wings
It is generally believed that, on slender delta wings, there is a critical state at which strong asymmetric vortices are found along the leading edge on the lee-side of the delta wing. These asymmetric vortices can lead to high lateral forces even when slender delta wing is at the zero angle of yaw. Some experimental studies reported recently, cast considerable doubt as to the validity of the a...
متن کاملA survey of Laser Range Finding
This report provides a informal survey of laser distance measurement. Applications of laser range finding are briefly discussed and various techniques for laser ranging such as active laser triangulation, pulsed time-of-flight (TOF), phase shift, FMCW, and correlation are described.
متن کاملTwin Plate Weir: A Flow Measuring Device (TECHNICAL NOTE)
For efficient use of water, accurate measurement of flow in (field/laboratory) channels is required for many water resource projects. The present work is aimed to study the flow characteristics of a twin plate weir (two sharp-crested plates are placed one behind the other at some distance) under free and submerged flow conditions. Experiments are performed with four spacing of the twin plate we...
