Research Opportunities

Our main tools are Matlab and CodeV.

Based on optics to design, create and verify a real system or an end product.

You can learn lots of optical testing methods and know how to use the interferometer.

We also have 3D printer to make it more convenient to build a prototype or the experiment requied adapter.

If you're interested in optical system, testing and design, welcome to our lab.
