摘要：
A new laser displacement sensor has been designed, constructed, and used in a train running at a speed of 64km/h. The laser displacement sensor is insensitive to ambient light and to temperature. The parameters of the laser displacement sensor are as follows: the measurement range is 20 mm, and the laser displacement sensor resolution is 0.3 mm. All the results show that this new displacement sensor meets the requirement for real-time gauge measurement. (c) 2007 Elsevier Ltd. All rights reserved.
