Aiming at a defined point of the test object, the measuring beam of the single-point laser doppler vibrometer acquires vibrations at the point of impact.
Displacement, velocity and acceleration of the surface in the direction of the beam are measured up to 160 million times per second. This allows high precision measurements of these quantities achieving resolutions of up to 0.05 pm, 1.7 nm/s, and 1.8 ug, respectively.
The OptoMET single-point vibrometers combine the laser source, the interferometer and digital processing in a single enclosure and are thus the most compact laser Doppler vibrometers of their performance class. Operation is intuitive via a touch-sensitive display on the rear of the enclosure and by means of ergonomic rotary buttons for changing the measuring ranges.
The highly integrated UltraDSP signal processing delivers extremely low-noise measurement data that is output via an advanced Ethernet interface. At the same time, a dedicated BNC port for each measurement parameter is available for integration into existing analog measurement environments. All vibrometers can be combined with a choice of optical systems and decoders for optimum adaptation to specific measurement requirements.
Vibrometry in the short-wave infrared range for maximum signal-to-noise ratio. Necessary for dark or rough surfaces, biological tissue as well as long working distances.
Infrared laser Doppler vibrometer with compact fibre-coupled measuring head. Ideal for confined spaces, in climatic chambers or with extreme exposure to radiation.
