A zip-line consists of a pulley suspended on a cable mounted on an incline. It is designed to enable a user, propelled by gravity, to traverse from the top to the bottom of the inclined cable by holding on or attaching to the freely moving pulley. Zip-line tours are becoming popular vacation activities and ride managers often implement a high speed camera system to photograph riders during their decent.
One zip-line company (Xplor) has selected a high-speed, long-distance rangefinder to improve the timing of their photographs. The Acuity Distance Measurement Sensor (model AR3000) uses an eye-safe laser to track the position of moving targets. Accurate to within centimeters, the sensor takes distance samples every 0.5 milliseconds. The sensor device is configured to transmit a voltage output signal at a set alarm point location within the sensor’s 300 meter range. This output signal triggers the high-speed camera to photograph the rider at exactly the right moment. Contact Acuity for more information about high-speed distance rangefinders and to discuss your unique sensor applications.
