Sound and Bright‘s Modulo Uno is a compact, single-detector laser-ultrasound receiver. This unit uses S&B’s innovative Multi-Channel Random Quadrature. MCRQ takes advantage of light interference for accurate, high-quality interferometry and characterisation of samples.
Modulo Uno detects both polarisations of light within the same array as the beam is not split, allowing it to operate at lower laser powers than the Quartet.
Lower laser power makes the Modulo Uno ideal for sensitive materials testing.
The idea behind Multi-Channel Random Quadrature was to develop a laser-ultrasound technology with a robust, compact design and a large depth-of-field capable of functioning effectively in a wide range of environments without loses in sensitivity, including on rough surfaces. With support from the National Science Foundation and NASA, we developed a novel interferometric design. By collecting and processing a multitude of speckles, the Modulo is fully functional in environments which would otherwise be unsuitable for most other laser ultrasound instruments.
