Adjoint‐Designed Mosaic Optical Fourier Surfaces for Short‐Distance Red‐Green‐Blue Color Mixing From Spatially Separated Emitters
Short‐distance color mixing from spatially separated red, green, and blue (RGB) emitters is challenging in compact display optics. Here, we demonstrate an adjoint‐designed, fabrication‐constrained mosaic optical Fourier surface (OFS) for RGB homogenization at a 5 mm observation distance. A 3 mm 3 mm aperture comprise...
