Ultra High Resolution Four-wave Interferometric Sensor1

BOJIONG a leading Ultra High Resolution Four-wave Interferometric Sensor manufacturer and supplier in China, supports precise measurement and analysis of optical performance. Our products are widely used in key areas such as aerospace, optical manufacturing, energy research, and biomedical. We have established a sound operating mechanism. We look forward to establishing sincere cooperative relationships with global customers to jointly create outstanding achievements.

Compared to traditional microlens array Hartmann sensors, the BOJIONG Ultra High Definition Four-wave Interferometric Sensor not only offers more phase points, ensuring high resolution and the ability to reveal detailed features in measurements, but also has a wider adaptive bandwidth and a greater dynamic range, enabling it to meet a broader range of measurement needs and conditions.

The ultra-high definition resolution of the BOJIONG sensor reaches 512×512 (262,144 phase points), complemented by its wide spectral response from 400 to 1100 nanometers, ensuring high accuracy and reliability under various optical conditions. Moreover, it supports the display of 10 frames of full-resolution real-time 3D results, providing users with immediate, dynamic measurement outcomes, which significantly enhances work efficiency.

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.
