<b>Single Shot Exposure Bracketing for High-Dynamic Range Imaging using a Multifunctional Metasurface</b>

<p dir="ltr">We propose a hardware driven solution to high dynamic range (HDR) imaging in the form of a single metasurface lens. Our design consists of a metasurface capable of forming nine low dynamic range (LDR) sub-images of varying intensities scaling by a factor of 2 onto an imaging sensor. After synthetically verifying the functionality of our design, the metasurface is fabricated and a prototype system is constructed for real world experiments. Utilizing the experimental system, the compatibility of our extracted LDR sub- images with pre-existing exposure bracketing solutions for multi-image HDR fusion is demonstrated. The resulting HDR images are highly robust to scene motion due to the instantaneous capture of multi-exposure LDR sub-images allowing for HDR video capabilities.</p>
