Abstract
Virtually all optical systems have some possible interpretation as a visual optical system. Often though, a detector such as a vidicon or photographic film intercedes to record the image. In such cases several quantitative methods have been devised to specify the required aberration content and fabrication tolerances for the optics used in such systems. Direct visual systems are the oldest of optical systems, but generally lack a good quantitative basis for tolerance specification. This condition has been accepted because the human eye is a remarkably adaptive organ, which will accept imagery that appears to be unacceptable by many of the accepted quantitative measures. On the other hand, the eye is bothered by such defects as scratches, digs and other cosmetic errors that are not consequential to many other optical systems.
