Farewell to the complex optical path and low resolution! FIS4 wavefront sensor brings three disruptive innovations to optical system

In the field of wavefront sensing, the technical limitations of Hartmann Shack (HS) sensor are increasingly prominent: complex optical path, low resolution, and harsh conjugation requirements. Since March, 2018, the team of Professor Yang YONGYING from Zhejiang University, after seven years of dedicated research and development, has made three revolutionary breakthroughs in FIS4 wavefront sensor, and is redefining the new standard of high-performance wavefront detection!

01 core breakthrough: the ultimate solution to the three technical bottlenecks 

02 why is FIS4 a better choice?

✅ Breakthrough 1: completely bid farewell to the complex light path

HS pain point: the strict conjugate requirements of deformable mirror and sensor lead to complex optical path design and difficult debugging

FIS4 wavefront sensor

● installation at any position: no need to conjugate with deformable mirror, greatly improving the integration flexibility

● optical path length reduced by 70%: system volume reduced by more than 50%

● commissioning time from hours to minutes: reduce system integration time

✅ Breakthrough 2: fully built-in self interference optical path

HS pain point: external interference light Louie is disturbed by the environment and has poor stability

FIS4 wavefront sensor

● self interference Design: all optical paths are integrated in 70 × 46mm module

● anti vibration performance increased by 10 times: stable operation in 5hz-200hz vibration environment

● plug and play: no need for professional optical debugging personnel

✅  Breakthrough 3: the order of magnitude improvement of physical resolution

HS pain point: microlens array limited resolution (typical 32 × 32 ≈ 1024 points)

FIS4 wavefront sensor

● 512 × 512 phase points (262144 data points)

● nanometer phase sensitivity: RMS repeatability ≤ 0.001 λ

● high order aberration analysis: support up to 64 Zernike coefficient analysis

03 revolutionary breakthrough in application scenarios

✅ Adaptive optics system

Traditional limitations: the conjugate requirements of HS sensors limit the degree of freedom of system design

FIS4 wavefront sensor solution: deploy anywhere and easily integrate existing systems.

✅ Industrial online detection

Traditional limitations: HS sensor has poor vibration resistance and cannot adapt to the production line environment

FIS4 wavefront sensor solution: the ordinary optical table can work stably and adapt to the factory environment.

✅ Space optical applications

Traditional limitations: HS sensors are bulky and heavy, and are not suitable for aerospace applications

FIS4 wavefront sensor solution: 50% reduction in volume and 60% reduction in weight, suitable for aerospace applications.

FIS4 wavefront sensor is not a simple technical iteration, but a fundamental innovation of traditional wavefront detection. When you are still compromising for complex optical path design, low resolution data and harsh environmental requirements, FIS4 has provided a new solution.

Jinnaike optoelectronics and Yucheng optical sensor will continue to expand the wavelength coverage and technical boundary of FIS4 four wave interferometric sensor, and provide more flexible detection solutions for customers in the fields of semiconductor, aerospace, biomedicine and so on.
