    摘要: Methods and systems for forming a displacement scale comprising TIR prisms on a substrate are described. A system for forming the displacement scale includes one or more rollers having a pattern of total internal reflection (TIR) prism features in negative relief. As the rollers are rotated, the scale is formed on the substrate. The rollers may also include pattern features in negative relief. Rotation of the rollers simultaneously forms the displacement scale and the pattern features on the substrate. The TIR prism features of the displacement scale may be oriented to provide measurement of one or more of lateral displacement, longitudinal displacement and angular displacement.

    摘要: Optical films having anti-Moiré and anti-wetout features are described, along with systems and methods for making these optical films. A master used to make optical films is formed using a single axis actuator cutting along a trajectory that is out of plane with the surface of the master. Movement of the cutting tool along the trajectory cuts grooves having variable depth and variable pitch into the surface. Prisms formed from the master have variable depth, variable height prisms that provide anti-wetout and anti-Moiré features.

    摘要: In one aspect, the invention provides a light control film having an indicium visible at a range of viewing angles. The light control film comprises a light input surface and a light output surface opposite the light input surface. The control film further comprises alternating transmissive and absorptive regions disposed between the light input surface and the light output surface. Each absorptive region has a height and a length, wherein the heights of the absorptive regions corresponding to the indicium are different that the heights of the absorptive regions that surround the absorptive regions corresponding to indicium.
