Various embodiments of the disclosure comprise an eye imaging system including an eye imaging apparatus and an eye imaging computing apparatus. The eye imaging apparatus can be configured to receive a plurality of images of the eye with a same field of view while each portion of the eye is illuminated time-sequentially. The image computing apparatus can comprise an image processing unit configured to combine the plurality of images into a composite image. Various embodiments of the disclosure comprise a syntactic image analyzing method. The syntactic image analyzing method can comprise aligning a plurality of images of an eye with a same field of view and combining the plurality of images into a composite image. The image analyzing method can further comprise analyzing each image by identifying a boundary line of a clear portion and gradually removing an unclear portion in each image.

Eye imaging apparatus with sequential illumination and a syntactic image analyzing method

Various embodiments of an eye imaging apparatus are disclosed. In some embodiments, the eye imaging apparatus may comprise a light source, an image sensor, a hand-held computing device, and an adaptation module. The adaptation module comprises a microcontroller and a signal processing unit configured to adapt the hand-held computing device to control the light source and the image sensor. In some embodiments, the imaging apparatus may comprise an exterior imaging module to image an anterior segment of the eye and/or a front imaging module to image a posterior segment of the eye. The eye imaging apparatus may be used in an eye imaging medical system. The images of the eye may be captured by the eye imaging apparatus, transferred to an image computing module, stored in an image storage module, and displayed in an image review module.

Eye imaging apparatus and systems

Various embodiments of an eye imaging apparatus can be used to image the posterior and/or anterior portions of the eye. In some embodiments, the eye imaging apparatus can comprise a light source, imaging optics, an image sensor, and a handgrip comprising a bump shaped to fit with a palm of an operator. In some embodiments, the eye imaging apparatus can comprise a light source, imaging optics, an image sensor, and a control button. The control button can comprise a multi-functional button and/or a control button activated by the index finger. In some embodiments, the eye imaging apparatus can comprise a housing structure comprising a double shell structure with an inner shell and an outer shell, which can be configured to facilitate heat management. In some embodiments, the eye imaging apparatus can comprise a removable front imaging module, a main module, and an interconnect locking structure configured to enable repeated removal of the front imaging module from and re-attachment of the front imaging module to the main module. Various embodiments also comprise a carrying case for an eye imaging apparatus.

Mechanical features of an eye imaging apparatus

An eye imaging apparatus can include a housing, an optical imaging system in the housing, and a light source in the housing to illuminate an eye. The optical imaging system can include an optical window at a front end of the housing with a concave front surface for receiving the eye as well as an imaging lens disposed rearward the optical window. The apparatus can comprise a light conditioning element configured to receive light from the light source and direct said light to the eye. The apparatus can further include an image sensor in the housing disposed to receive an image of the eye from the optical imaging system. In various embodiments, light conditioning element includes at least one multi-segment surface. In some embodiments, the housing is provided with at least one hermitic seal, for example, with the optical window. In some embodiments, time sequential illumination is employed.
