  • Publication number: 20170020389
    Abstract: A system automatically captures a fundus image with limited user interaction such that the fundus image has one or more desired characteristics. The system can retrieve at least one image from an image capture device, process the at least one image digitally to generate a processed image, detect at least one point of interest in the processed image, determine that each of the at least one point of interest is representative of a corresponding feature of the eye, and obtain a fundus image of the eye based on the at least one image.

  • Patent number: 9345407
    Abstract: A system that incorporates teachings of the present disclosure may include, for example, a method for aligning first and second light signals on an optical path directed to a target, where the first light signal provides a visualization of the target, and a portion of the second light signal reflects from at least one subsurface of the target. The method also includes aligning a first focal point of the first light signal and a second focal point of the second light signal, where the first focal point is at least in a first proximate location of the second focal point, and adjusting a first position of the first and second focal points to be in at least a second proximate location of the target without adjusting the at least first proximate location of the first focal point relative to the second focal point. Other embodiments are disclosed.
