← HistoryWhich effect limited accuracy of medieval astrolabes involving early pinhole cameras?
A)Chromatic aberration of objective lens
B)Diffraction blurring internal images
C)Spherical aberration from pinhole edges✓
D)Coma distorting off-axis targets
💡 Explanation
Spherical aberration impacts astrolabe pinholes because light refracts differently near pinhole edges, blurring final images; therefore precision declines at smaller apertures rather than diffraction limiting resolution as the system approached theoretical perfect imagery if corrected.
