Melarosa Cam Site

where ((u,v)) are mask coordinates, (A) the amplitude transmission (≈ 1), (\phi) the designed phase profile, and (\lambda) the wavelength (centered at 550 nm). Propagation to the sensor plane (distance (d)) yields the PSF

| 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

Here’s an interesting write-up on — a name that seems to sit at the crossroads of digital identity, online presence, and creative expression. where ((u,v)) are mask coordinates, (A) the amplitude
