Abstract

In damage tests conducted on rabbit and monkey eyes, the threshold values for retinal damage resulting from different laser radiation were determined. The reproduction of the "worst-case" situation was ensured by the test apparatus. All physical parameters, such as power/energy, exposure time, and retinal spot, were carefully controlled. Probit analysis showed a very precise determination of the threshold values based on ophthalmoscopical visibility. The attempt of a simple physical interpretation of the thresholds leads to contradictions in major points, so a detailed calculation of damage functions and thermal model calculations are necessary.

摘要

在对兔眼和猴眼进行的损伤测试中,确定了不同激光辐射导致视网膜损伤的阈值。测试设备确保了“最坏情况”的再现。所有物理参数,如功率/能量、曝光时间和视网膜光斑,都得到了仔细控制。概率分析表明,基于检眼镜可见度能非常精确地确定阈值。对阈值进行简单物理解释的尝试在要点上会产生矛盾,因此有必要对损伤函数进行详细计算并进行热模型计算。
