Lenticular optics are segmented repetitive optical structures, usually formed on thin sheets. Multiple lenticular, diffusing and other sheets are used together in display and lighting applications. Though the performance of such stacks can be predicted by generic Monte-Carlo methods, such methods are slow and approximate. We have invented much faster methods for simulating systems of multiple sheets of lenticular optics, diffusers, polarizers, scatterers, etc.
A geometric optics solver creates an input-output model of each individual lenticular sheet. These individual models are then coupled using linear feedback theory. We may also imagine the final solution to be the steady state distribution of a certain Markov chain.
This solver converges in seconds and gives great accuracy, whereas ray tracing may take approximately an hour. With this performance improvement, hundreds of thousands of optical combinations may be tried to search for the best optical solution (which creates a required optical light output with the minimum input energy).
