Abstract
Optical measurement of straylight in the human eye is a challenging task. Issues such as illumination geometry, detector sensitivity and dynamic range as well as various inherent artifacts must be addressed. We developed a novel instrument based on the principle of double-pass optical integration adapted for fast measurements in a clinical setting. The experimental setup was validated using four different diffusers introduced in front of the eyes of ten subjects. Measurement limitations and future implications of rapid optical measurement of straylight in ophthalmic diagnosis are discussed.
摘要
人眼杂散光的光学测量是一项具有挑战性的任务。诸如照明几何形状、探测器灵敏度和动态范围以及各种固有伪像等问题都必须加以解决。我们基于双程光学积分原理开发了一种新型仪器，适用于临床环境中的快速测量。使用在十名受试者眼前引入的四种不同扩散器对实验装置进行了验证。讨论了眼科诊断中杂散光快速光学测量的测量局限性和未来意义。
