摘要:
Apparatus (10, 100) for obtaining images of the retina (12) of an eye (14) comprising: a lighting device that includes a light source capable of producing light in a plane (24, 34, 134), emanating light from a point (46, 146) so that the lighting device is capable of illuminating a circumferential line on the retina; a support structure; and one or more detectors (60, 160) to detect the light reflected from the retina to produce an at least one-dimensional image of the retina, in which the lighting device can be pivotally mounted on the support structure and can rotate around of an axis (18, 118) that is substantially in said plane, so that, in use, the lighting device can be rotated around the axis to obtain a plurality of one-dimensional images of the retina, and in which the device The illumination further comprises a scanning transfer device (40, 140), in which the scanning transfer device has two focuses and the point is provided at a first focus (48, 148) of the scanning transfer device and the sweeping transfer device is adapted to be positioned so that the pupillary point (20) of the eye is housed in a second focus (50, 150) of the scanning transfer device and the device Scan transfer vo is adapted to transfer light in a plane from the point inside the eye.Aparato (10, 100) para obtener imágenes de la retina (12) de un ojo (14) que comprende: un dispositivo de iluminación que incluye una fuente de luz capaz de producir luz en un plano (24, 34, 134), emanando la luz desde un punto (46, 146) de manera que el dispositivo de iluminación es capaz de iluminar una línea circunferencial sobre la retina; una estructura de soporte; y uno o más detectores (60, 160) para detectar la luz reflejada desde la retina para producir una imagen al menos unidimensional de la retina, en el que el dispositivo de iluminación puede montarse de manera pivotante en la estructura de soporte y puede rotar alrededor de un eje (18, 118) que se encuentra sustancialmente en dicho plano, de
