Damage detection of railway tracks based on vibration measurements by moving laser sensors

BackgroundRailway transportation plays a key role in mass transportation of products and passengers. One of the biggest problems that endanger safety and operation of railways is the fractural cracks of the railway tracks. Even though ultrasonic measurement techniques have been extensively used for detection of such defects, these methods may show inefficiencies....
