Abstract

In this work, we proposed a grating optimization method for waveguide type head-up display based on the multilayer perceptron network classification, which achieves rapid prediction and optimization of an interlayer grating structure. Compared with existing grating structures, the optimized grating has a coupling efficiency of 73% at wavelengths of 450 nm, 532 nm, and 637 nm simultaneously. The uniformity of diffractive efficiency can reach 0.84 within the 400–650 nm range, ultimately achieving color uniformity within a single-layer waveguide over a 15° field of view angle range. This method also provides ideas for optimizing other types of grating waveguide structures.
