High Resolution Four-wave Interferometric Sensor

The high-resolution four-wave interferometric sensor is a highly efficient interferometric measurement tool specifically tailored for industrial applications, scientific research, and national defense sectors.

With its outstanding performance, this sensor offers a high resolution of 300×300 (90,000) phase points and a wide spectral response range of 400-1100nm, ensuring precision and reliability in various optical measurement scenarios.

Its unique technical features include the use of patented random coded four-wave diffraction technology, which allows the sensor to achieve self-interference in a single measured wavefront and to produce interference at the rear image plane position, without the need for complex phase-shifting techniques.

Moreover, BOJIONG's sensor is capable of displaying 3D results in full resolution at 10 frames per second in real-time, suitable for laser beam wavefront detection, adaptive optical systems, optical system calibration, optical window inspection, as well as measurements of optical plane and spherical shapes, including surface roughness and micro-profile detection.

With its easy operation, ultra-high vibration resistance, and stability, this sensor from BOJIONG provides an ideal wavefront sensing measurement solution, achieving nanometer-level precision measurements without the need for vibration isolation, significantly enhancing measurement efficiency and accuracy.
