Modelling Surface Light Scattering in the Context of Freeform Optical Design
Vì C. E. Kronberg, Martijn J. H. Anthonissen, Jan H. M. ten Thije Boonkkamp +1
We present a novel approach of modelling surface light scattering in the context of freeform optical design. The model relies on energy conservation and optimal transport theory. F…
Numerical Methods for the Hyperbolic Monge-Ampère Equation Based on the Method of Characteristics
Maikel W. M. C. Bertens, Ellen M. T. Vugts, Martijn J. H. Anthonissen +2
We present three alternative derivations of the method of characteristics (MOC) for a second order nonlinear hyperbolic partial differential equation. The MOC gives rise to two mut…
Design of a freeform two-reflector system to collimate and shape a point source distribution
A. H. van Roosmalen, M. J. H. Anthonissen, W. L. IJzerman +1
In this paper we propose a method to compute a freeform reflector system for collimating and shaping a beam from a point source. We construct these reflectors such that the radiant…
A Simple and Efficient Stochastic Rounding Method for Training Neural Networks in Low Precision
Lu Xia, Martijn Anthonissen, Michiel Hochstenbach +1
Conventional stochastic rounding (CSR) is widely employed in the training of neural networks (NNs), showing promising training results even in low-precision computations. We introd…
