  • Abstract
  • Look Inside

 A description is given of a device which enables observation of images projected upon the retina. In the past, such observation were possible only when the objects were lines or dots. The basic principle is as follows:

 The incident ray enters the eye in such a way that it forms as sharp an angle as pos-sible with the emergent ray. Next, an optical observation instrument is installed where it dose not interfere with the light, and is focused on the projected image upon the retina. The visual angle of the instrument must be as wide as possible.
