The high resolution and wide wavelength range of the BOJIONG Near-Infrared Four-wave Interferometric Sensor make it an ideal choice for scientific research and industrial applications, especially in situations that require precise measurement and analysis. The sensor is capable of high-precision wavefront measurement within the 900nm to 1200nm wavelength range, with a resolution of 512×512 pixels (a total of 262,144 phase points). Its design takes into account the need for anti-vibration and stability in practical applications, allowing for high-precision measurements without the need for complex environmental control. This greatly simplifies the operation process and improves measurement efficiency.

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.
