 Details

Bojiong FIS4 HR-W wavefront detector was developed by a team of professors from Zhejiang University and Nanyang Technological University, Singapore. The 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. It is specially developed for convenient interferometric measurement in industry, scientific research, and national defense. With high resolution of 300×300 (90,000) phase points, wide spectral response of 400-1100nm, and 10 frames of full-resolution real-time 3D result display, it provides an ideal wavefront sensing measurement tool for beam wavefront detection, adaptive optics, optical system calibration, optical window detection, optical plane surface shape, spherical surface shape measurement, surface roughness, and surface microscopic profile detection.

FIS4 HR-W uses patented random coded four-wave diffraction technology to achieve self-interference of a single-channel measured wavefront, and interference occurs at the rear image plane position. It has low requirements on the coherence of the light source, does not require phase shifting, and can achieve interferometric measurement using an ordinary imaging system. It has ultra-high vibration resistance and ultra-high stability, and can achieve nm-level precision measurement without vibration isolation. Compared with the microlens array Hartmann sensor, it has more high-resolution phase points, a wider adaptive band range, a larger dynamic range, and better cost performance.
