Research and development

Crash tests are one of the favourite areas of application because here the large measuring ranges of up to 1500 mm available in a possible bandwidth of 20 kHz allow carriage movements or deformations of parts inside vehicles to be mea­sured without contact. The high scanning rate of 50 kHz is also required to measure the valve stroke within the scope engine testing at maximum speeds. Much lower measuring frequencies are required for using the laser in the digitisation of components for body development.

Here the laser sensor replaces the tactile probe of the z-axis on measuring machines with the advantage of much higher measuring speeds at a greater data volume for one thing because movement can take place continuously in x and y direction.
