Product Description

During flow field and wind tunnel testing, there is a need for ultra high-speed detection equipment. Bojiong has introduced the Ultra High Speed Wavefront Sensor. This device features ultra-high vibration resistance, ultra-high stability, and ultra-high-speed imaging capabilities, enabling nano-level precision measurements without the need for vibration isolation. It has low requirements for the coherence of the light source and does not require phase shifting. Interferometric measurements can be achieved using ordinary imaging systems.

BOJIONG Ultra High-speed Wavefront Sensor Details

BOJIONG Ultra High-speed Wavefront 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.
