- fudged71 1y agoTaking a peek at the research: “While flat-optics cameras have transitioned from theoretical concepts to high-fidelity laboratory prototypes, significant interdisciplinary R&D—spanning nanofabrication, materials science, computational imaging, and systems integration—is required to realize commercial flat camera modules for next-generation smartphones. Recent breakthroughs have produced multilayer metalenses only ~0.5 mm thick that can focus unpolarized broadband light across several discrete wavelengths. Dual-Pixel Coded Aperture (CADS): End-to-end learned amplitude masks on dual-pixel sensors have shown >1.5 dB PSNR gains in all-in-focus images and 5–6% depth accuracy improvements in DSLR, endoscope, and dermoscope prototypes. Color-Coded Aperture Imaging: Single-lens, single-frame depth sensing via color-coded apertures has been demonstrated on DSLR and preliminary smartphone modules with depth map extraction sufficient for basic AR and portrait modes.”
