Abstract
The invention provides a manned centrifuge visual dysfunction detection device and detection method. The device comprises a lamp target of an arc-shaped structure, wherein the lamp target comprises acentral lamp and a group of peripheral lamps symmetrically arranged on the two sides of the central lamp, and the lamp target further comprises a plurality of groups of view lamps symmetrically arranged on the outer sides of the peripheral lamps and used for receiving external control signals and controlling the on-off of the view lamps according to the control signals. By implementing the invention, a plurality of groups of view lamps symmetrically arranged on the outer sides of the peripheral lamps are added, so that the detection range is expanded to -60 degrees to 60 degrees, and the accuracy of detecting the peripheral view angle of a to-be-detected person is improved.
Description
technical field [0001] The invention relates to the field of detection of visual dysfunction, in particular to a detection device and method for visual dysfunction of a manned centrifuge. Background technique [0002] The manned centrifuge can generate continuous acceleration to meet the ground anti-overload training requirements of the personnel to be tested. Under the action of continuous acceleration, the blood of the human body flows toward the soles of the feet along the inertial direction, resulting in a decrease in arterial blood pressure in the head, and hypoxia in the brain tissue is prone to occur. At this time, visual dysfunction is prone to occur, which usually occurs before brain dysfunction. Therefore, in manned centrifuge acceleration physiological training, the end point of acceleration endurance is generally judged by the loss of peripheral vision and central vision of the test personnel, and visual impairment is used as one of the indicators for judging the...
