Four-point speckle-interferometer for vibration analysis up to 60 MHz
The Modulo Quatro is a versatile multi-point laser interferometer based on Multichannel Random Quadrature (MCRQ) technology.
It has four measurement channels, each representing an independent measurement point, and can either pass four detection points through a single optical head or use four independent optical heads. Measuring points that are close together increase the scanning speed significantly (x 4), while separate optical heads enable the simultaneous measurement of different angles to determine the 3D component.
Thanks to the MCRQ technology mentioned above, this is achieved without the need for high-precision optical components or positioning, making the device particularly robust.
The Modulo Quatro has a multi-mode fiber design.
The Quatro can also be connected directly to a computer, which simplifies the measurement process. No external oscilloscope or A/D card is required, making it a versatile and efficient solution for ultrasonic measurements while maintaining precision and ease of use.
