Abstract
The window substantially has the shape of a dome. The optical observation device includes means of optical conjugation of the observed field with a plane of observation and means for relatively orienting the observation plane with respect to said field. Optical correction means are provided so as to correct aberration defects. According to the device, system, and method, said optical correction means are arranged between said windows and said relative orientation means in such a way that said optical correction means form an optical system with said window, which is at least substantially afocal.
