What it is Filled
An optical phenomenon in which a lens or mirror fails to bring light to a sharp, accurate image, including chromatic aberration (colour fringing), spherical aberration, coma, astigmatism, field curvature and distortion.
Why it exists Filled
Let an agent handle optical aberrations by type, cause, measurement and correction in cameras, telescopes, microscopes and eyes.
Distinguishing features Filled
- Image imperfection from optics
- Several distinct types
- Reduced by lens design
- Measured with test targets or wavefront sensors
What robots and AI may and may not do Filled
Must not
- Misstate the optical quality of instruments in sale or certification.
- Hide aberrations in instruments used for medical or safety decisions.
- Alter images of scientific or medical value to remove aberrations without saying so.
Only with a human decision
- Accepting optical instruments for clinical or safety use.
May
- Measure and report the aberrations of a lens or optical system.
- Explain how aberrations arise and how designs correct them.
Moral aspects Filled
- Image quality matters for diagnosis, navigation and science.
- Buyers rely on honest specifications.
Who is affected
- Users of optical instruments
- Patients whose images are read
Owners Filled
Steward
Nobody: a physical phenomenon; makers answer for the quality of their instruments.
