Ultraviolet Four-wave Interferometric Sensor1

BOJIONG Optoelectronics has always been dedicated to wavefront interference detection technology, and now introduces a new generation of Ultraviolet Four-wave Interferometric Sensors, providing excellent solutions for universities and research institutes. Our products and services are widely used in optical manufacturing, aerospace, biomedical, and energy research, helping customers conduct precise measurements and analyses of optical performance to improve 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. BOJIONG sincerely invites customers from both domestic and international markets to collaborate with us to achieve brilliance together.


The Ultraviolet Four-wave Interferometric Sensor incorporates our proprietary technology of randomized coding four-wave diffraction, enabling interference at the back focal plane with minimal requirements for the coherence of the light source, thus eliminating the need for phase shifting. Through the ultraviolet imaging system, the sensor is capable of real-time wavefront measurement, exhibiting excellent vibration resistance and stability, and can achieve nanometer-level precision measurements even without the use of vibration isolation. BOJIONG Optoelectronics is poised to redefine the standards for optical performance measurement and analysis, leading the industry into a new era of precision and efficiency.

BOJIONG Ultraviolet Four-wave Interferometric Sensor Details

 

BOJIONG Ultraviolet 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.
