• abstract: High Dynamic Range (HDR) imaging is a technique that utilizes various exposure levels to produce high-quality images through a series of algorithms. Here, we present a microaperture modulated ultrathin array camera that enables single-shot HDR imaging through microfabrication. The camera consists of microaperture arrays, microlens arrays, and CMOS ISA (CMOS image sensor array) with an 800 μm total track length (TTL). The camera features a microaperture size within 4-stops that is suitable for HDR imaging result according to each stop. This miniatured camera offers a novel perspective on imaging with higher contrast ratio.
