Abstract: A light control film includes a two-dimensional array of projections arranged across the light control film. A square of a magnitude of a Fourier transform frequency spectrum of the projections includes a plurality of distinct peaks separated by one or more valleys. The peaks and the one or more valleys have respective averages Pavg and Vavg, Pavg/Vavg≥5, such that when light from a substantially Lambertian light source is incident on the light control film, the light control film transmits the incident light with the transmitted light propagating along a transmission axis and having an intensity profile having a full width at half maximum of less than about 120 degrees in each cross-section of the intensity profile that comprises the transmission axis.

Abstract: Systems and methods for designing and optimizing tools are provided. A computational fluid dynamics (CFD) simulation model implemented by a processor is provided to simulate a fluid flow inside the tool to generate a particle density distribution of fluids inside the tool. The particle density distribution is converted to a spatial distribution of fluid concentration of the mixture which allows for high resolution visualization of fluid flow in the tool.
