Instrument for rapid measurement of the optical properties of the eye in the entire field of vision

摘要

An instrument measuring optical properties of an eye in an entire field of vision, including refraction and aberrations, including: a frame mounted on an ophthalmologic table that can be oriented in three perpendicular directions X, Y, Z; a support surface for a head of the subject; a hot mirror; a long mirror; an illumination sub-assembly including a fiber optic head; a lens; a diaphragm; a beam splitter; and a measurement sub-assembly with two lens and two mirrors; a camera including a matrix of micro-lenses on the inlet of camera, the camera being placed on the focal plane of the micro-lenses; the frame including a motor, a shaft of which rotates in the Y direction, to which an arm is attached that can rotate on the shaft; components of the illumination sub-assembly, components of a measurement sub-assembly, and the camera with the matrix of micro-lenses being mounted on the arm.

主权项

1. An instrument measuring optical properties of an eye in an entire field of vision, including refraction and aberrations, comprising:
a support surface for a head of a subject on whose eyes measurements are to be performed, within a plane of a pupil of the eye; a frame mounted on an ophthalmologic table that can be oriented in three perpendicular directions X, Y, Z, with the X, Z directions being on a same plane and the Y direction being perpendicular to the plane of the directions X, Z, a hot mirror and a long mirror being united to the frame and placed in front of the head of the subject; and an optical assembly comprising an illumination sub-assembly including a fiber optic head, a lens, a diaphragm, a beam splitter, and a measurement sub-assembly including two lenses, two mirrors, and a camera including a matrix of micro-lenses on its inlet, the camera being placed on a focal plane of the micro-lenses, wherein the frame includes a motor mounted on it, a shaft of which rotates in the Y direction, to which an arm is attached that can rotate with the shaft, and such that a conjugated plane of the micro-lenses coincides with a rotation axis of the shaft, and wherein the optical assembly is mounted on the arm for rotational movement, the focal plane of at least one of the two lenses of the measurement sub-assembly coinciding with the plane of the pupil of the eye.
