Description
Technical field
The present invention relates to a kind of flight trainer, particularly a kind of vision blind spot demonstration and paracentral fixation instrument for training.
Background technology
Night-flying training is the important means that combat effectiveness of the troops generates, noctovision more and more receives the concern of aviation medicine worker, along with the reduction of ambient light illumination, the physiological mechanism of vision there occurs very large change, the visual performance between noctovision and daytime is caused to differ widely, the former depends primarily on the function of rod cell, and the latter depends primarily on the function of cone cell, cone cell department high light and color are felt, about there are 7,000,000, mainly concentrate on macular area, and only have cone cell at center recess, the neuronic transmission in this district connects in single line again, therefore vision is very sharp, and namely cone cell density significantly reduces after leaving central fovea, play a role during its main bright light environments.The rod cell department low light level and achromatic vision, about have 1.2*10
8individual, rod cell center recess lack as, start occur and increase gradually apart from central fovea about 2 °, the most intensive at about 10-25 °, then reduce gradually again to periphery.Just because of characteristic and the characteristic distributions of photoreceptor cell，photosensory cell, cause the feature that noctovision is exclusive, namely there are two blind spots in it, and one is night vision centrocecal scotoma, and two is intrinsic physiological blind spot.When the threshold value of environmental light brightness lower than cone cell, during eyes direct-view target, because center recess ignores rod cell, within the scope of central region 1 °, there is a blind spot for this reason, be referred to as night vision centrocecal scotoma.And aircrew is when night flying search target, get used to direct-view target and go to find, and target easily drops on blind spot exactly when looking at straight.Physiological blind spot is then because on retina, optic nerve leaves retina, goes out eyeball position to visual centre transmission, and herein without photoreceptor cell，photosensory cell, therefore the visual field is rendered as intrinsic dark space, the position of blind spot is about 3mm place at the nasal side at macula lutea center, and it exists all the time.Due to two things soon time normal, side blind spot can be compensated by offside vision, so aircrew does not perceive in the visual field of oneself have a place without the region of visual experience.But under special circumstances, as an an eye line be blocked time, can occur.But lack effective training equipment and method all the time, cause most of aircrew can not recognize the existence of these two blind spots, this is for flight, and danger is extremely fatal.
Summary of the invention
In order to solve noctovision physiologic training Problems existing, the invention provides the demonstration of a kind of vision blind spot and paracentral fixation instrument for training, can effectively help aircrew to recognize physiological blind spot and the cecocentral existence of night vision, for it provides the training the most effectively watching mode (paracentral fixation) attentively, to improve the fighting capacity of aircrew's night search target capability and night flying.
