Abstract: A binocular scanning laser ophthalmoscope (SLO) is used to track the fixational eye movement of each of the eyes of a subject. The binocular SLO may include right eye optics for imaging a portion of the retina of the right eye and left eye optics for imaging a portion of the retina of the left eye.

The right eye optics and left eye optics may be separate imaging paths, each with its own bi-directional MEMS scanning mirror and Keplerian telescope. The use of the MEMS scanning mirrors minimizes the size and weight of the binocular SLO.

The illumination optical system irradiates a fundus with light from the light source. The imaging optical system forms an image of the fundus on the image sensor. An optical axis of the illumination optical system does not match an optical axis of the imaging optical system, or the illumination optical system does not have a specific optical axis.

Abstract: In an embodiment, multiple conjugate planes are used to create a plurality of optical pupil planes and a plurality of image planes. These optical planes solve multiple problems and introduce significant performance enhancements in the system. In one implementation of a disclosed embodiment, the measurement channel is based on the reverse Shack-Hartmann principle. By introducing a relay system (for example a 4-f lens system) the slit plane could be made conjugate to the measured system pupil plane (unlike a previous implementation where the slits were places away from the pupil plane as it was not accessible directly). Creating a virtual pupil plane allows for more accurate placement of the plane without the need for contact with the measured optical system.

A separation between the spots indicates that the focus is away from the target surface, while overlapping spots indicate the focus is at or on the target surface.
