Laser Sensors Gather Information During Crash Tests

The AR500 laser position sensor has been used to measure a car’s deceleration

Engineers of automobile crash tests use the AR500 laser position sensor to measure the car’s deceleration during the crash event. Analog signals from the sensors are used to produce a deceleration curve plotted against time. The laser sensors, mounted directly to the vehicle, undergo the full impact of the crash, often up to 80 G's. Despite the force of the impact, no AR500's have ever suffered damage!  Based on successful facility testing, MIRA (The Motor Industry Research Association) now recommends the use of AR500 laser sensors for documenting statistics of vehicle crash tests.

Crash Test Laser Sensors

September 11, 2012

Engineers of automobile crash tests use a variety of sensors to record a wealth of vehicle information during the last, split-seconds of the controlled impact. Vehicle deformation, accelerations, temperatures, etc, are collected at high speeds and analyzed to determine avenues for improvement in safety. - Read Article
