Title
(EN) MINIATURE SIMULTANEOUS VISION SIMULATOR INSTRUMENT
(ES) INSTRUMENTO MINIATURIZADO SIMULADOR DE VISIÓN SIMULTÁNEA
(FR) INSTRUMENT MINIATURISÉ SIMULATEUR DE VISION SIMULTANÉE
Abstract
(EN)
The invention relates to a miniature simultaneous vision simulator instrument with various image-forming channels, each one of which projects, onto the retina of the same eye, a component image with a different degree of defocusing of the same observed object, such that the superposition of all of the component images forms a final simultaneous vision image on the retina of the eye. The instrument has at least one adjustable variable focus lens which, as the focus is changed, modifies the vergence of the light beam passing through said adjustable lens. Furthermore, one of the image-forming channels passes through the adjustable variable focus lens. The instrument can operate in the modality of optical channels which are physically differentiated in the modality of temporal channel multiplexing.

Además uno de los canales formadores de imagen atraviesa la lente ajustable de focal variable. El instrumento puede funcionar en la modalidad de canales ópticos físicamente diferenciados en la modalidad de multiplexación de canales temporales.

L'invention concerne un instrument miniaturisé simulateur de vision simultanée avec plusieurs canaux formateurs d'image, chacun desdits canaux projetant dans la rétine d'un même oeil une image composante avec un degré distinct de défocalisation d'un même objet observé, de manière que la superposition de toutes les images composantes forme dans la rétine de l'oeil une image finale de vision simultanée. Ledit instrument comprend au moins une lentille réglable à focale variable qui lors d'un changement de focale modifie la convergence du faisceau lumineux qui traverse ladite lentille ajustable. En outre, un des canaux formateurs d'image traverse la lentille réglable à focale variable. L'instrument peut fonctionner en mode de canaux optiques physiquement différenciés, en mode de multiplexage de canaux temporels.
