Speed Measurement by Optical Techniques
The most obvious optical method for measuring the speed of a moving object is to use the Doppler effect: light reflected from the moving object will be shifted in frequency on proportion to the line of sight velocity of the object. While we are familiar with examples in the radio domain (such as police traffic radar and Doppler weather radar) and with acoustic waves (the apparent change in pitc...
متن کاملOptical Speed Measurement and applications
Mobile robot navigation is a well researched discipline, looking back to a relatively long history however it is still a rich, active area for research and development. The ultimate goal for robots and intelligent vehicles seems to be autonomous navigation in complex real life scenarios. In order to achieve higher levels of autonomy sophisticated sensors and a sound understanding of the robot a...
متن کاملInfluence of Traverse Speed on Surface Irregularities Created by the Abrasive Waterjet
The paper deals with the calculation of the optimal traverse speed for diff erent types of materials, which is very important for predication, imaginings and dimensioning of technological factors and selection of the materials with the aim to increase of surface quality at abrasive waterjet cutting (AWJ) technology. The surface irregularities of the experimental used materials AISI 304, AISI 30...
متن کاملPrecision Speed Measurement by Light
Driving Assistance Systems combine a variety of sensors with vehicle display, control and handling capabilities to improve driver performance and safety. As part of a project to evaluate new driving assistance systems using environmental sensors, engineers at Renault needed to measure the exact car speed in real time with better than 0.1 km/h accuracy. Common existing solutions are based on eit...
