载人潜水器操作屏幕的暗适应评估研究

Safety is critical to the dive work of manned submersibles. It is particularly important to reduce the potential threat to safety caused by visual obstacles during the operation and to shorten the dark adaptation reaction time of submariners. Dark adaptation is an important visual factor affecting the operation of submariners. Repeated switching and adaptation to high-contrast brightness environments will prolong the dark adaptation time of human eyes, thereby affecting the safety and accuracy of submersible operations. In this paper, aiming at the lighting environment of submarine operation area, according to the transition lighting method, the transition screen lighting is used to compensate the dark adaptation reaction time of human eyes under harsh lighting conditions. In the experiment, by changing the brightness level of the transition screen and the observation time, the optimal brightness and time range of the transition lighting were evaluated to achieve visual optimization and ensure the safety of the submariners′ operation.
