Abstract: An ocular alignment system for aligning a subject's eye with an optical axis of an ocular imaging device comprising one or more guide light and one or more baffle configured to mask the one or more guide light from view of the subject such that the one or more guide light is only visible to the subject when the eye of the subject is aligned with the optical axis of an ocular imaging system.

Abstract: In certain embodiments, an ophthalmic system includes an anamorphic depth gauge (ADG) device and a computer. The ADG device measures the z-location in the interior of an eye and includes a detector array arranged at an oblique angle with respect to the z-axis. The array generates a detector signal in response to detecting a light beam, which has a z-focus in the interior of the eye. A set of line focus optical elements focuses the light beam to form a line focus on the detector array, and a set of nominal focus optical elements focuses the light beam to form a nominal focus on the detector array. The computer: generates an image using the detector signal; determines the position of the nominal focus on the line focus according to the image; and determines the z-location of the z-focus from the position of the nominal focus on the line focus.

Abstract: In certain embodiments, an ophthalmic laser surgical system for imaging and treating a target in an eye includes a digital micromirror device (DMD) confocal microscope, a laser device, and a computer. The DMD confocal microscope generates of images of the eye and includes a light source, a DMD device, and an image sensor. The light source provides a microscope imaging beam. The DMD device directs the microscope imaging beam along an imaging path towards the eye, receives the microscope imaging beam reflected from the eye, and rejects light of the reflected microscope imaging beam that is not from an image plane to scan the microscope imaging beam. The image sensor detects the scanned microscope imaging beam to generate the images of the eye. The laser device directs a laser beam along a laser beam path towards the target in the eye.

Abstract: In certain embodiments, an ophthalmic laser surgical system for imaging and treating a target in an eye includes an imaging system. The imaging system includes a scanning laser ophthalmoscope (SLO) device and an optical coherence tomography (OCT) device. The SLO device generates SLO images, and the OCT device generates OCT images. The SLO device and the OCT device share a scanning system and a light detector. The scanning system scans SLO and OCT imaging beams within the eye. The light detector detects the SLO and OCT imaging beams reflected from the eye and generates SLO and OCT signals in response to detecting the imaging beams.

Abstract: Aspects of the present disclosure provide improved techniques to assist imaging and/or measuring a subject's eye that are suitable for use in an imaging and/or measuring apparatus operated by the subject, even in the absence of a clinician or technician, thereby improving access to medical grade imaging and/or measurement. Some aspects relate to techniques for receiving user input and capturing a medical grade image and/or measurement of a subject's eye responsive to receiving the user input. Some aspects relate to techniques for providing visual feedback to a user of an imaging and/or measuring apparatus indicating a location of a subject's eye in a field of view of the imaging and/or measuring apparatus. Some aspects relate to techniques for selectively illuminating a first portion of a subject's eye with illumination light and capturing an image of the first portion of the subject's eye.

Abstract: Systems of the present disclosure may include one or more of an optical overlay device, which may include one or more of an imaging optic to receive incoming light from a scene, and project at least a portion of the incoming light onto an imaging sensor; an imaging sensor to transduce into image data the light projected onto it by the imaging optic; a processing engine electrically coupled with a non-transitory computer readable medium having machine readable instructions stored thereon, which, when executed by the processing engine, cause the system to: generate a scaled overlay image based on the image data and a magnification parameter; a display device configured to project the scaled overlay image through a display optic toward a portion of a beam-combiner; a coupling mechanism to enable releasable attachment of the optical overlay device with a primary viewing device.
