Lenticular Sheet Generated Optical Patterns for Aircraft ...
Barbieri, Nicholas
Under proper conditions, lenticular sheets can generate visual patterns which are usable as a navigational aid. A distant observer can use this navigational aid to precisely determine its relative position. The navigational aid is constructed by mounting a lenticular sheet over a pattern of periodically spaced lines sharing the sheet's period. This configuration results in the appearance of lines perpendicular to the original pattern, which ar...
