Abstract
Объектив "Рыбий глаз" для видеокамеры, содержащий расположенные по ходу лучей из пространства предметов на одной оптической оси две группы линз - с отрицательной и положительной оптическими силами, и апертурную диафрагму, расположенную между двумя группами, отличающийся тем, что группа линз с отрицательной оптической силой состоит по ходу лучей из пространства предметов состоит из двух отрицательных выпукло-вогнутых менисков и одиночной положительной линзы, а группа линз с положительной оптической силой состоит по ходу лучей из пространства предметов из одиночной положительной линзы и двухлинзового положительного компонента со склеенными поверхностями между указанными двумя линзами, причем фокусное расстояние объектива определяется его угловым полем и параметрами матрицы видеокамеры по формулеf=aN/2W,где а- размер элемента матрицы видеокамеры в миллиметрах, N - число элементов матрицы на меньшей стороне и 2W - угловое поле объектива в радианах.A fisheye lens for a video camera containing two groups of lenses located along the rays from the space of objects on the same optical axis - with negative and positive optical forces, and an aperture diaphragm located between the two groups, characterized in that the group of lenses with negative optical power consists along the rays from the space of objects consists of two negative convex-concave menisci and a single positive lens, and a group of lenses with positive optical power consists along the rays from the expanse objects from a single positive lens and a two-lens positive component with glued surfaces between the two lenses, the focal length of the lens being determined by its angular field and the parameters of the video camera matrix using the formula f = aN / 2W, where a is the size of the video camera matrix element in millimeters, N is the number matrix elements on the smaller side and 2W is the angular field of the lens in radians.
