Precision Control of Web Material having Micro-replicated Lens Array |
摘要 |
A manufacturing system includes a sensing system that provides high-resolution feedback for web guiding and tension control. The system may be especially useful for web material that is manufactured to include micro-replicated structures with micron size scale. A micro-replication station forms a pattern of micro-replicated lenses on a web material. The sensing system illuminates a measurement area on the web material and detects an angular distribution of light exiting a set of the micro-replicated lenses within the first measurement area. A control system that adjusts at least one process control parameter of the transport system based on the detected angular distribution.
