SUMMARY
The discussion centers on the phenomenon of pincushion distortion caused by spherical detectors in imaging systems. Users noted that while the shape of the detector influences the final image, the expected outward bending of lines does not occur; instead, lines bend inward, creating pincushion distortion. This distortion is contrasted with field curvature, which is a different optical aberration. Understanding the geometric implications of spherical detector shapes is crucial for accurate image interpretation.
