"scaling small image to large windshield adds massive empty data to calculation, consuming too much memory/ too slow for real-time driving... overcome using Matrix Multiplication based diffraction method acting as mathematical zoom lens calculating display chip/ windshield requirements independently... 58% reduced calculation time, significantly less memory usage by eliminating redundant 0 data, can project images at vastly different sizes/ distances simultaneously without driver's eyes constantly refocusing"
