Method and device for generating retinal images using the stigmatism of the two foci of a substantially elliptical sight

A method for generating retinal images using the stigmatism of two foci of a substantially elliptical diopter comprising a semi-reflecting surface, said method comprising:

• positioning in the vicinity of the first focus of said substantially elliptical diopter:
• a luminous display, each object point of which generates a beam first of all convergent before reflection on the semi-reflecting surface of said substantially elliptical diopter, and then parallel in the vicinity of the pupil of the eye,
• positioning in the vicinity of the second focus of said substantially elliptical diopter, a so-called “image”focus formed by the pupil or the centre of the eye of the observer, and
• projecting in the vicinity of the retina of the eye of the observer, the image generated by said luminous display and reflected by the semi-reflecting surface of said substantially elliptical diopter.

A device for generating retinal images, using the stigmatism of two foci of a substantially elliptical diopter comprising a semi-reflecting surface, comprising:

• a so-called “source”focus formed by:
• the diaphragm of a pin diaphragm forming a convergence point of an image generated by a luminous display, or a light source,
• a so-called “image” focus formed by the pupil or the centre of the eye of the observer, positioned in the vicinity of the second focus of said substantially elliptical diopter,
• a projection in the vicinity of the retina of the eye of the observer, of the image generated by said luminous display of by said light source, and reflected by the semi-reflecting surface of said substantially elliptical diopter.
