Abstract:
1. A method for replicating a colorimetric resonant reflectance sensor grating pattern, the method comprising: (a) advancing a substrate supply roll until a substrate roll section is produced; (b) applying a liquid between the substrate roll section and a tool having the pattern to form a substrate roll section with a liquid layer; (c) rolling a shuttle mechanism having a pressure roller such that the substrate roll section with the liquid layer is rolled between the pressure roller and the tool, wherein the shuttle mechanism advances in a direction to cover the tool with the substrate roll section with a liquid layer while the substrate supply roll remains stationary, (d) wherein the pattern on the tool is transferred to the liquid layer to create a pattern coated substrate; (e) hardening the pattern coated substrate to form a cured pattern substrate; (f) detaching the cured pattern substrate from the tool by retracting the shuttle mechanism while the substrate supply roll remains stationary; (g) depositing a dielectric film on the cured pattern substrate.
