AI Article Synopsis
- A new way to design a special recording system for making patterns called gratings is explained.
- This method uses a technique called ray-tracing to better create the shape of mirrors used in the system.
- It allows for different mirror shapes, which means it can make more accurate designs for the recording structures.
Article Abstract
A reconstruction design method for an aspherical recording system for varied line-space gratings is introduced. This method converts the recording system design from achieving specific groove distribution coefficients within the expansion model into reconstruction of the auxiliary mirror surface via the ray-tracing method. The effects of higher-order expansion terms in the expansion model are investigated and more accurate design of the varied line-space grating recording structure is achieved. By varying the surface reconstruction target, this method can be used to design aspherical recording structures with any auxiliary mirror surface shapes.
