Laser Displacement Sensor

The Distortion Analyzer equipped with a laser displacement sensor becomes a powerful vibrometer providing dc and ac components of up to 50 kHz. The laser sensor gives access to the mechanical domain, simplifies the T/S parameter measurement and is the basis for the vibration and radiation analysis. Only a laser sensor based on the triangulation principle measures the dc component of the displacement reliably, which is a very valuable symptom for loudspeaker nonlinearities. This dc capability is also the basis for scanning the geometry of a radiator. 

A variety of laser sensor heads is provided to get optimal performance in the particular application.

It is recommended to use coating spray for micro-speakers and tweeters with transparent and shiny diaphragms. More information.undefined
