Eye imaging system and method

Abstract

The invention discloses an eye imaging system and method, which relate to the field of ophthalmological optics instruments and are used for eliminating ghosts during eye examination and imaging at high quality. The system comprises a light source module (101), a light-splitting module (102), a common light path module (103), eyes (104), eye grounds (105), an image receiver (106), a light source power supply module (201), an image receiver driving module (202), a controlling and processing display module (203) and a motion driving module (204), wherein the motion driving module (204) is connected with and used for synchronously driving the light source module (101) and the image receiver driving module (201) to move; and light rays of the light source module (101) are reflected to the image receiver (106) for exposing after being used for scanning the eyes (104), so that the light rays are spliced, processed, imaged, displayed or record by using the controlling and processing display module (203). The system and the method are mainly applied to eye ground examination.

Description

Technical field [0001] The invention relates to the field of ophthalmic optical instruments, in particular to a system and method for eye imaging. Background technique [0002] At present, optical instruments for eye detection or photography generally include an illuminating light path and an observation light path. The illuminating light path is used to illuminate the eyes of the observer, and the reflected light illuminates the observer’s eyes or observation device through the observation light path. It is used to observe and photograph the health of the eyes including the fundus. [0003] However, due to the complex structure of the patient’s eyes, the specific physiological tissues are also diverse, especially when optical instruments are used for observation and photographing. In many cases, the excess reflected light from the cornea and the surface of the eye lens will form ghost images after passing through the optical instruments, thus It reduces the overall image quality ...

AI Technical Summary

Problems solved by technology

[0005] 1. Ghosting and stray light cannot be completely eliminated, and the resulting image quality is still poor

[0006] 2. The illumination light path and observation light path are independent, and the cost is high

[0007] 3. The optical structure for eliminating ghost and stray light is relatively complex and bulky

[0008] 4. When the annular diaphragm is used, the utilization rate of the light source is low, so the energy consumption is relatively large

[0009] 5. The luminous flux entering the patient's eyes is relatively large, which may easily cause eye discomfort for the patient

[0010] At present, there is no imaging system and method that overcomes the above defects, has higher imaging quality, relatively simple structure, low cost, less energy consumption, and less side effects on patients' eyes.
