A retinal imager for imaging a retina of an eye includes an illumination source operable to generate illumination light and a beam splitter operable to receive the illumination light and direct the illumination light along an optical axis. The retinal imager also includes a field lens disposed along the optical axis and an objective lens disposed along the optical axis and operable to contact a cornea of the eye. An aerial image is formed adjacent to the field lens. The retinal imager further includes an image sensor and one or more lenses disposed along the optical axis between the beam splitter and the image sensor. The one or more lenses are operable to form a sensor image at the image sensor.

Aspects of the present disclosure provide improved techniques for imaging a subject's retina fundus. Some aspects relate to an imaging apparatus that may be substantially binocular shaped and/or may house multiple imaging devices configured to provide multiple corresponding modes of imaging the subject's retina fundus. Some aspects relate to techniques for imaging a subject's eye using white light, fluorescence, infrared (IR), optical coherence tomography (OCT), and/or other imaging modalities that may be employed by a single imaging apparatus. Some aspects relate to improvements in white light, fluorescence, IR, OCT, and/or other imaging technologies that may be employed alone or in combination with other techniques. Some aspects relate to multi-modal imaging techniques that enable determination of a subject's health status. Imaging apparatuses and techniques described herein provide medical grade retina fundus images and may be produced or conducted at low cost, thus increasing access to medical grade imaging.

A system includes a base, and an actuator having a first end and a second end. The system also includes a shaft configured to rotate relative to the base, and a drive link fixed to the shaft. The system further includes a support arm. A first end of the support arm being fixed to the shaft such that rotation of the shaft causes commensurate rotation of the support arm. The system also includes a timing link having a first end pivotably connected to the base and a second end opposite the first end. Additionally, the system includes a mount coupled to the second end of the timing link. The mount is configured to maintain a substantially constant orientation relative to the base as the support arm transitions between a raised position and a lowered position.

Compact telescope configurations for light scanning systems and related methods are disclosed. According to an aspect, a system for imaging or relaying an image of an object includes a first optical element having a first focal length f.sub.1 for imaging or relaying an image of an object at the distance f.sub.1 from the first optical element. The system also includes a second optical element having a second focal length f.sub.2 for receiving an image of the object from the first optical element and for focusing an output of the image at the distance f.sub.2 from the second optical element on a side that opposes the first optical element. The first optical element and the second optical element are separated by a distance of approximately [Formula I], wherein r is the finite radius of curvature of the wavefront of light located at the object or image of the object.

An eye-imaging apparatus and system is described including circular fiber array ends arranged at skewed angles relative to the optical axis of the imaging path, a light intensity distribution converter along the illumination path to convert a bell-shaped distribution into a top-hat distribution, an image sensor, and high frequency response light source(s) operating in flash illumination mode in synchronization with the image sensor. As a result, unnecessary exposure of illumination light to a patient eye is minimized while the illumination light can span a wide enough coverage range with desired intensity and spectral distribution to cover the desired angular field of view and spectral range on a retina.

An apparatus for producing a fundus image includes: a processor and a memory; an illumination component including a light source and operatively coupled to the processor; a camera including a lens and operatively coupled to the processor, wherein the memory stores instructions that, when executed by the processor, cause the apparatus to capture fundus images and provide controls for re-imaging the fundus.

Optical coherence tomography (OCT) imaging systems, handhold probes, and methods that use a field curvature to match a curved surface of tissue are disclosed. According to an aspect, an OCT imaging system includes optical elements to generate diverging light. The system also includes one or more mirrors and a lens system configured to scan the diverging light onto a curved surface of an object for imaging of the object.

A clinician eye camera apparatus, networked system, and medium, are disclosed herein, comprising: 1) a camera unit comprising an outer housing, and enclosing: a) a front PCB with a plurality of LED's and a middle aperture to fit a rear camera lens; b) a middle camera filter unit, comprising a plurality of light filters, and a servo motor with a propeller that rotates the light filters into position in front of a rear camera lens; c) the rear camera lens connected to a CMOS sensor, a rear PCB, and a battery; 2) a pivotable arm assembly comprising a top end unit attachable to the camera unit, and a middle handle unit pivotably attached to an arm unit. The arm assembly can be used in a straight handheld mode; or bent 90 degrees for mounting in a slit lamp. Images are transmitted to a clinician computer and/or a remoter server.

A system and method for a portable eye examination camera is described herein. The system and method may include: a light source disposed within said portable camera at a set distance away from an eye of a patient; a first lens within said portable camera for focusing the light from said light source onto a retina of the eye and providing a wide field retinal image; a second lens for receiving said retinal image and causing a magnification of said retinal image; and a digital camera within a mobile computing device for recording said retinal image.

A modular lens adapter system or kit is provided for mobile anterior and posterior segment ophthalmoscopy. Equipped with various lens adapter modules, respective lenses and a mobile imaging device, a user is provided with tools for various mobile ophthalmoscopy imaging applications. Eye care practitioners can use their existing lenses to customize the modular lens adapter system in a cost-effective way, which allows for mobile and remote capture, viewing, and utilization of clinical images. The various modules are also adaptable to nearly any type of phone or tablet regardless of its dimensions or presence of a protective case. The invention also addresses the need for fewer, smaller, less expensive, and easier to use ophthalmic imaging equipment, which is further important in enabling a broad base of users.
