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, Adopting domestic patented technology, this sensor combines diffraction and interference to achieve four-wave transverse shear interference, offering superior detection sensitivity and vibration resistance.

It can perform real-time, high-speed dynamic interferometry without vibration isolation, with a real-time measurement frame rate exceeding 10 frames. The FIS4 sensor's measurement range covers 200nm to 15μm, featuring an ultra-high phase resolution of 512×512 (260,000 phase points). It has measurement repeatability better than 1/1000λ (RMS) and a sensitivity of 2nm.

This sensor is suitable for laser beam quality analysis, plasma flow field detection, real-time measurement of high-speed flow field distribution, optical system image quality evaluation, microscopic profile measurement, and quantitative phase imaging of biological cells.
