Visual Systems and Afocal Systems

15.1  VISUAL OPTICAL SYSTEMS

In visual optical systems, the final image detector is the human eye. Some special considerations must be made when designing these systems, for example, the eye resolution, which is approximately 1 arcmin near the fovea. Another important characteristic is the fact that the eye moves rotating in its socket. Third, the eye has the capacity of focusing, which is called accommodation. These systems will be studied in this chapter. More details can be found in the book by Walker (2000).

15.1.1  EXIT PUPIL LOCATION IN VISUAL OPTICAL SYSTEMS

The final image in a visual instrument is formed at the retina of a human eye. If the eye is emmetropic, that is, if it does not have any refractive ...
