Application of rangefinder for small forest fire detection
"... Detection of fire smoke plume with a compact cheap rangefinder based on 905 nm laser diode (2 μJ pulse energy, ∅2 cm telescope and 720 m solid-target range) is demonstrated. Reliable detection of small experimental fires (20×25 m2 fire plot, burning rate of ~3 kg/s) is achieved for the range of abou ..."

of about 255 m. A theoretical model of the mixing of burning products with air in the wind, based on three-dimensional system of Navier-Stokes equation and commercial software PHOENICS, is developed. The model predicts 220 m range of smoke detection by the rangefinder, indicating good agreement between
Profiling of Hot Surfaces By Pulsed Time-of-Flight Laser Rangefinder Techniques
- Applied Optics
, 1993
"... The possibilities for using the pulsed time-of-flight laser radar technique for hot refractory lining measurements are examined and formulae are presented for calculating the background radiation collected, the achievable signal to noise ratio and the measurement resolution. An experimental laser ra ..."

W. The single shot resolution is about 60 mm (sigma value), but it can be improved to mm range by averaging techniques over a measurement time of 0.5 s. A commercial laser radar profiler based on the experimental laser radar device is also presented, and results obtained with it in real measurement
A REAL-TIME LOW RESOLUTION RANGE-FINDER FOR ROBOTIC APPLICATIONS
"... A 5x5 photo-diode commercially available array has been used in order to build up a low-cost low resolution real-time range finder which is suitable for robotic applications like obstacle detection, since its purpose is to retrieve three-dimensional information from the close environment. The laser ..."

Bayesian Estimation of Distance and Surface Normal with a Time-of-Flight Laser Rangefinder
, 1999
"... We describe a Bayesian estimation method for measurement of both range and surface orientation using a laser range finder. The method not only provides more accurate estimates of range for dark surfaces that are difficult to measure, but also simultaneously provides estimates of surface normals. Thi ..."

. This paper describes our efforts for a commercially available sensor, the laser rangefinder Acuity AccuRange 3000 LIR, a widely available device. We detail the Bayesian techniques, sensor calibration, and the processing required. 1.
Comparison of Scanning Laser Range-finders and Millimetre-wave Radar for Creating a Digital Terrain Map
"... Scanning infra-red laser range finders and millimetre-wave radar have seen extensive application in automation and other mapping scenarios in a wide range of research and commercial environments. There has, however, been relatively limited use of these sensing technologies in the mining industry. ..."

A Compact and Low-Power Two-Axis Scanning Laser Rangefinder for Mobile Robots
"... In this paper we present a prototype two-axis scanning laser rangefinder, or LIDAR, intended for use on small mobile robots. By combining a high speed, highly accurate single point laser range sensor with a custom high speed, compact scanning mechanism, we have developed a sensor which can provide ..."

"... Range imaging offers an inexpensive and accurate means for digitizing the shape of three-dimensional objects. Because most objects self occlude, no single range image suffices to describe the entire object. We present a method for combining a collection of range images into a single polygonal mesh t ..."
