A waveguide apparatus includes a planar waveguide and at least one optical diffraction element (DOE) that provides a plurality of optical paths between an exterior and interior of the planar waveguide. A phase profile of the DOE may combine a linear diffraction grating with a circular lens, to shape a wave front and produce beams with desired focus. Waveguide apparati may be assembled to create multiple focal planes. The DOE may have a low diffraction efficiency, and planar waveguides may be transparent when viewed normally, allowing passage of light from an ambient environment (e.g., real world) useful in AR systems. Light may be returned for temporally sequentially passes through the planar waveguide. The DOE(s) may be fixed or may have dynamically adjustable characteristics. An optical coupler system may couple images to the waveguide apparatus from a projector, for instance a biaxially scanning cantilevered optical fiber tip.

A method of identifying iris includes: providing incident beams entering an eye locating at a reference position; setting a first, a second and a third reference point for locating the eye at the reference position; forming a first, a second and a third measuring glint by the incident beams after the eye moves from the reference position to a measuring position, and positions of the first, the second and the third measuring glint corresponding to the positions of the first, the second and the third reference point; capturing an eye image including a first, a second, a third measuring glint image and an iris image; comparing the gray scale value with a threshold gray scale value to obtain the positions of the first, the second and the third measuring glint; and calculating a first and a second variation to obtain an resolution variation of the iris image.

A device for monitoring eye movement and pupil response that comprises a first optical pathway for displaying one or more images to the eyes of a patient and a second optical pathway for obtaining images of the eyes of a patient. The device further comprises at least one screen for displaying an image to the left eye of the patient which is not visible to the right eye of the patient and for displaying an image to the right eye of the patient which is not visible to the left eye of the patient; a first camera for capturing images of the left eye of the patient; and a second camera for capturing images of the right eye of the patient at substantially the same time as the first camera is capturing images of the left eye of the patient. The device also comprises at least one IR light source for illuminating the eyes of the patient; and a processor for processing the obtained images and measuring pupil response and/or eye movements.
