HR High resolution wavefront sensor

As a long-term focus on High Resolution Four-wave Interferometric Sensor technology, BOJIONG Optoelectronics, our products and services are widely applied in various fields such as optical manufacturing, aerospace, biomedical, and energy research. By providing precise optical performance measurement and analysis, we assist our customers in enhancing product quality and production efficiency. In recent years, we have continuously expanded our production scale, strengthened our technical capabilities, and established a comprehensive corporate operating mechanism. We sincerely invite customers from both domestic and international markets to collaborate with us to achieve brilliance together.

The BOJIONG HR High Resolution wavefront sensor employs patented random coded four-wave diffraction technology to enable self-interference ahead of a single measured wavefront, with interference occurring at the rear image plane position. This sensor can achieve interference measurements using a standard imaging system, which demands minimal coherence from the light source and eliminates the need for phase shifting. It exhibits extraordinary vibration resistance and stability, facilitating nanometer-level precision measurements without the need for vibration isolation. In comparison to microlens array Hartman sensors, the BOJIONG HR High Resolution wavefront sensor offers a higher resolution of phase points, a broader adaptable bandwidth, a larger dynamic range, and a more favorable cost-performance ratio.

High Resolution Four-wave Interferometric Sensor Details

 

Developed by a collaboration of professors from Zhejiang University and Nanyang Technological University of Singapore, the BOJIONG HR High resolution wavefront sensor leverages domestic patented technology to merge diffraction and interference for achieving standard four-wave transverse shear interference. This sensor excels in detection sensitivity and anti-vibration capabilities, enabling real-time and high-speed dynamic interferometry without the need for vibration isolation, with a frame rate exceeding 10 frames for real-time measurements.

The FIS4 sensor within this system boasts an ultra-high phase resolution of 512×512, amounting to 260,000 phase points. It has a measurement range from 200nm to 15μm, a sensitivity of 2nm, and a repeatability that is superior to 1/1000λ (RMS). This advanced sensor is versatile for applications such as laser beam quality analysis, plasma flow field detection, real-time high-speed flow field distribution measurement, optical system image quality assessment, microscopic profile measurement, and quantitative phase imaging of biological cells.
