PRISM PITCH OPTIMIZATION

摘要

An optical display system is disclosed. The system has an optical light source, a first microstructured optical component having a plurality of first microstructures, and having a nominal first microstructure pitch, P1; and a second microstructure optical component, arranged relative to the first microstructured optical component, having a plurality of second microstructures and having a second nominal microstructure pitch, P2. P2/P1 has a value closer to the mid-point between consecutive integers than to either one of the consecutive integers.
