| Component | Specification | Rationale | |-----------|---------------|-----------| | | 4 mm focal length, f/1.8 aspheric glass | Provides sufficient light gathering while keeping the form factor compact. | | Phase Mask | 150 µm thick fused silica, grayscale diffractive pattern (pixel pitch = 2 µm) | Encodes depth into PSF shape; manufactured via electron‑beam lithography; anti‑reflective coating (AR < 1 %). | | Sensor | 12 MP (4000 × 3000) back‑illuminated CMOS, 1.1 µm pixel size, global shutter | High spatial resolution needed to capture fine PSF variations; low read‑out noise (≈ 1 e⁻). | | Mechanical Housing | 3‑D‑printed aluminum frame, total thickness 8 mm | Rigid alignment, thermal management. | melarosa cam

has a rich heritage dating back to the 1960s (Mertz & Mertz, J. Opt. Soc. Am. 1965). Modern variations include the coded‑aperture snapshot spectral camera (Arce et al., IEEE TSP , 2014) and depth‑from‑defocus systems using programmable lenses (Wang et al., CVPR , 2020). Recent neural‑enhanced approaches such as Deep Phase‑Mask Imaging (Liu et al., SIGGRAPH , 2022) demonstrate that learned optics can be co‑designed with reconstruction networks. Ramos³, D
