High Resolution Four-wave Interferometric Sensor1

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 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.

High Resolution Four-wave Interferometric Sensor Details

 

BOJIONG High Resolution Four-wave Interferometric Sensor developed by a team of professors from Zhejiang University and Nanyang Technological University of Singapore, with domestic patented technology, it combines diffraction and interference to achieve a common four-wave transverse shear interference, with superior detection sensitivity and anti-vibration performance, and can realize real-time and high-speed dynamic interferometry without vibration isolation. The real-time measurement shows a frame rate of more than 10 frames.

At the same time, the FIS4 sensor has an ultra-high phase resolution of 512×512 (260,000 phase points), the measurement band covers 200nm~15μm, the measurement sensitivity reaches 2nm, and the measurement repeatability is better than 1/1000λ (RMS). It can be used for laser beam quality analysis, plasma flow field detection, real-time measurement of high-speed flow field distribution, image quality evaluation of optical system, microscopic profile measurement and quantitative phase imaging of biological cells.
