Description

Предметом изобретени   вл етс  устройство дл  измерени  видимости , действие которого основано на наложении на наблюдаемый контраст искусственной дымки переменной плотности, создаваемой вращающимс  диском с освещенными белыми зубцами, периодически и с больщой частотой перекрывающими лучи света, исход щие от объекта наблюдени .The subject of the invention is a device for measuring visibility, the action of which is based on imposing on the observed contrast an artificial haze of variable density created by a rotating disk with illuminated white teeth periodically and with a greater frequency that overlaps the light rays emanating from the object of observation.

Изменение плотности дымки, налагаемой на объект наблюдени , достигаетс  изменениел- времени пребывали  белой поверхности зубцов перед глазом наблюдател , дл  чего отношение ширины просветов к ширине зубцов сделано переменным вдоль радиуса диска. Измерение этим прибором сводитс  к определению по шкале радиуса окружности наблюдени , при котором обнаруживаетс  исчезновение объекта, так как плотность дымки соответствует величине радиуса.The change in the density of the haze imposed on the object of observation is achieved by a change in the time-effect of the white surface of the teeth in front of the observer's eye, for which the ratio of the width of the gaps to the width of the teeth is made variable along the radius of the disk. Measurement with this instrument is reduced to the determination on a scale of the radius of the observation circle at which the disappearance of the object is detected, since the density of the haze corresponds to the radius value.

Другим ко;-1структивным оформленном устройства  вл етс  вибрирующа  перед глазом наблюдател  белак п.ластинка с постепенно расшир ющимс  вырезом в виде треуго.льника. И в этом случае измерение сводитс  к определению такого места пыреза, при котором объект наблюдени  перестает быть видимь;:ч.Another co-ordinate-designed device is the white plate observer vibrating in front of the eye with a gradually expanding neckline in the form of a triangle. And in this case, the measurement is reduced to the determination of such a place of the fire nozzle, at which the object of observation ceases to be visible;

Диск с зубцами или пластинка ксистоуктив.ю могут быть выполнены из прозрачного или матового материала.A disc with teeth or a plate of histopath. Can be made of transparent or matte material.
