眼球多参数测量系统研究

Eye multi-parameter measurement system research

研究一种眼球多参数测量系统,该系统利用光学相干层析成像技术、光外差探测技术以及图像处理技术对眼球九项参数进行非接触式测量,这9项参数包括中央角膜厚度、前房深度、晶状体厚度、玻璃体厚度、视轴长度、视网膜厚度、白到白的距离、瞳孔直径和角膜曲率等。该系统探测深度和空间分辨率分别可达到毫米级和微米级,可实现眼球九项参数的精准测量,能够提供一种快速无损非接触的眼球参数测量方法,为测量眼球参数提供了一种非常重要的技术手段。

In this paper, we study a kind of eyeball multi-parameter measurement system, the system uses optical coherence tomography technology, optical heterodyne detection technology and image processing technology to non-contact measurement of eyeball nine parameters, the nine parameters includes the central Corneal Thickness, Anterior Chamber Depth, Lens Thickness, Vitreous Thickness, the Axial Length, Retinal Thickness,White to White, Pupil Diameter and Corneal Curvature, etc. The system detects the depth and spatial resolution can reach millimeter level and micro level respectively, which can realize the eye nine parameters precision measurement. In this paper, we study the eyeball multi-parameter measurement system can provide a rapid non-destructive methods for measuring the parameters of non-contact eye, parameters for measuring eye provides a very important technical means.
