Opto-thermal deformation fitting method based on a neural network and a transfer learning

Yue Pan,

et al.

Abstract: The thermal deformation fitting result of an optical surface is an important factor that affects the reliability of optical–mechanical–thermal integrated analysis. The traditional numerical methods are challenging to balance fitting accuracy and efficiency, especially the insufficient ability to deal with high-order Zernike polynomials. In this Letter, we innovatively proposed an opto-thermal deformation fitting method based on a neural network and a transfer learning to overcome shortcomings of numerical meth… Show more
