Details for Pixels per Square Inch (Display Area Density)
Introduction : Represents the total pixels packed into a square inch of screen space. A more intuitive metric for high-PPI displays than linear PPI.
History & Origin : Gained attention with 4K/8K screens and VR headsets (2010s), where pixel densities exceed 500 PPI (250,000+ pixel/in²).
Current Use : Key for VR/AR displays (e.g., 1M pixel/in² for retina-level immersion) and medical imaging monitors where detail is critical.
Details for Sample per Inch (Scanning Resolution)
Introduction : Measures how many samples a scanner takes per linear inch. Determines the fidelity of digitized images, especially for archival or forensic work.
History & Origin : Introduced with drum scanners in the 1970s. Later adopted for flatbed scanners, with high-end models reaching 4800+ SPI for film scanning.
Current Use : Essential in document digitization (300 SPI for text, 600+ SPI for photos), film scanning (2400+ SPI for 35mm negatives), and forensic image analysis.
