摘要： An autorefractor system in an ultra-compact package is described for rapidly and objectively measuring the refractive state of the eye. The autorefractor detector system, in conjunction with a secondary light source, uses one photodetector such as a charge coupled device (“CCD”) or one photodiode, to intercept a light beam at two distances from a secondary retinal light source created by one relay lens, one pupil emitter conjugate lens and one pupil detector conjugate lens, as well as a field lens. The signals produced by the photodetector are used to determine the full spherocylindrical refraction of the eye. A novel illumination and imaging system provides multiple capabilities to image the eye, control accommodation, and acquire and maintain optical alignment, while obtaining other measurements of the eye.

摘要： A device for mapping the visual field of an eye includes a projector for creating a light beam of visible light, a first light directing element for controlling the direction of the beam, and a reflection element for reflecting the light beam through a predetermined crossing point. The elements are arranged in such a way so that the light beam can be directed to well defined sites of the retina of the eye when positioned with the center of its lens substantially in the crossing point. The projector can be made to include a focusing element and a beam cross-section forming element for creating a disk of predetermined size on the retina of the eye.
