Robust & Versatile
The Quartet does not require high-accuracy components or positioning, making it exceptionally rugged.
Fiberised Optical Head
A relatively small and versatile fiberised optical head is easily mounted to fit a variety of measurement conditions, and can be set up for a wide range of stand-off distances. The front lens can be easily changed or replaced if necessary.
Measurement Precision
The Quartet produces an analogue signal that is proportional to surface displacement.
High Sensitivity on all Surface Types and Materials
Thanks to its multiple detectors and high transmission optics, the Quartet accomplishes efficient light collection and high sensitivity. This is true when the system is fitted with a moderately powerful laser thanks to low noise detectors and electronics. By detecting and processing many speckle interference signals, the Quartet achieves a stable demodulated signal even when processing a highly speckled beam. This means that it can perform measurements on any kind of surface, including rough, porous, rusted or mirror-like surfaces.
Rapid Inspection
Streamlined electronic processing allows the Quartet to perform single-shot measurements on fast-moving objects, at speeds up to meters per second.
Not Wavelength Dependent
The Quartet can be fitted with a range of internal laser wavelengths ranging from visible to infrared.
Signal Indicators
The Quartet incorporates visual and audible signal indicators designed to help the user optimise their measurement setup. The Quartet also includes an internal calibration signal allowing for a calibrated output at 100mV per nanometer of displacement.
