(FR) DISPOSITIF D'IMAGERIE DE LA RÉTINE AUTONOME, PORTABLE
Abstract
(EN)
A portable MEMS-based scanning laser ophthalmoscope (MSLO). In one example, the MSLO includes a laser illumination sub-assembly, a two-dimensional MEMS scanning mirror, a conic front objective, and a detector sub-assembly all disposed within a portable housing. A battery configured to provide power to components of the MSLO may also be included within the housing. In one example, the laser illumination sub-assembly includes at least one laser configured to generate in each of two orthogonal dimensions one or more illumination beams separated from one another by a predetermined angle of separation. The MEMS scanning mirror and conic front objective are configured to produce a two-dimensional area of illumination from the one or more illumination beams in each dimension and to direct the illumination from the scanning mirror to the eye to illuminate the retina.

L'invention porte sur un ophtalmoscope laser à balayage à base d'entrées multiples sorties multiples (MEMS) (MSLO) portable. Dans un exemple, le MSLO comprend un sous-ensemble d'éclairage laser, un miroir de balayage MEMS bidimensionnel, un objectif avant conique et un sous-ensemble détecteur tous disposés à l'intérieur d'un boîtier portable. Une batterie configurée pour fournir de l'énergie aux composants du MSLO peut également être incluse à l'intérieur du boîtier. Dans un exemple, le sous-ensemble d'éclairage laser comprend au moins un laser configuré pour générer dans chacune de deux dimensions orthogonales un ou plusieurs faisceaux d'éclairage séparés les uns des autres par un angle de séparation prédéterminé. Le miroir de balayage MEMS et l'objectif avant conique sont configurés pour produire une zone bidimensionnelle d'éclairage à partir du ou des faisceaux d'éclairage dans chaque dimension et pour diriger l'éclairage provenant du miroir de balayage vers l'œil afin d'éclairer la rétine.
