Techniques in numerical flowline optics concentrator design

Abstract
Techniques are discussed for characterising and manipulating light sources using 3D numerical flowline analysis. Hyperbolic curve fitting from flowline measurements is proposed as a means of extrapolating flowlines to the far-field for calculation of etendue. The concept of flowlines as edge-rays is broken down to demonstrate that it is possible to measure etendue of non-Lambertian light sources directly from flowlines, using a light field sampling approach. Practical applications for concentrator design are given for Lambertian and asymmetric non-Lambertian light sources.
