An Inverse Method for the Design of Freeform Double-Reflector Imaging Systems
Sanjana Verma, Lisa Kusch, Martijn J. H. Anthonissen +2
We propose an inverse method to design two-dimensional freeform imaging systems. We present the mathematical model to design a parallel-to-point double-reflector imaging system usi…
Inverse freeform design of a parallel-to-two-target reflector system
Pieter Braam, Jan ten Thije Boonkkamp, Martijn Anthonissen +3
We present an inverse method for transforming a given parallel light emittance to two light distributions at different parallel target planes using two freeform reflectors. The ref…
Three-Dimensional Freeform Reflector Design with a Microfacet Surface Roughness Model
Vì Kronberg, Martijn Anthonissen, Jan ten Thije Boonkkamp +1
This manuscript will unify inverse freeform reflector design and surface light scattering to design freeform reflectors with a scattering surface. We use microfacets, which are sma…
An Iterative Least-Squares Method for the Hyperbolic Monge-Ampère Equation with Transport Boundary Condition
Maikel W. M. C. Bertens, Martijn J. H. Anthonissen, Jan H. M. ten Thije Boonkkamp +1
A least-squares method for solving the hyperbolic Monge-Ampère equation with transport boundary condition is introduced. The method relies on an iterative procedure for the gradien…
