Approximation methods in the computer numerically controlled fabrication of optical surfaces, Part 2: mollifications

IMA Journal of Numerical Analysis, 1992
The process of grinding and polishing optical surfaces using a Computer Numerically Controlled machine produces a machine material removal profile. The profiles achievable by the machine depend on the nature of the tool used in the process, and the tool center motions.

Performance evaluation of partial differential equation models in electronic speckle pattern interferometry and the δ-mollification phase map method

Applied Optics, 2006
The ordinary differential equation (ODE) and partial differential equation (PDE) image- processing methods have been applied to reduce noise and enhance the contrast of electronic speckle pattern interferometry fringe patterns. We evaluate the performance of a few representative PDE denoising models quantitatively with two parameters called image ...

Solving two kinds of inverse source problems for the heat equations by a mollification regularization method with Dirichlet kernel

Mathematical Methods in the Applied Sciences
We study the inverse issues for the heat equations with spatial‐dependent source and time‐dependent source, respectively. In this work, the source identification issues are ill‐posed, and the numerical solutions (if they exist) are not continuously dependent on the data.
