驾驶员暗适应测试仪由单片计算机系统、暗箱、强光产生部分及视标显示等部分组成。被测者在强光刺激之后，进入黑暗状态。同时测试仪开始计时，至被测者看清视标时停止计时。所计得的时间为其暗适应时间。测试仪测试的结果可显示在显示器上也可由打印机打印。实测结果表明驾驶员的暗适应时间有较显著的差异 Driver Dark Adaptation Tester by the single-chip computer system, dark boxes, glare produced part of the visual display and other components. Subjects in the light stimulation, into the dark state. Tester at the same time began to count, to be measured when the subject stopped watching time. The calculated time is its dark adaptation time. Tester test results can be displayed on the monitor can also be printed by the printer. The measured results show that the driver’s dark adaptation time has more significant differences
