Iris, английский
- The part of a lens that is used to control the amount of light that passes through the lens and onto the imaging device.
- Механика диафрагмы, которую можно регулировать вручную или автоматически для регулировки диафрагмы объектива.
- The mechanical device that adjusts to vary the amount of light passing through the lens of a camera.
- An adjustable aperture built into a camera lens to permit control of the amount of light passing through the lens.
- Mechanism within a lens to regulate the amount of light that passes through, and falls upon, the image sensor. it can be controlled manually or automatically.
- A means of controlling the size of a lens aperture and therefore the amount of light passing
- Механическая диафрагма которая может управляться вручную или автоматически для регулировки отверстия объектива.
- Improved rotor isolation system
- Infrared imaging seeker
- Infrared interferometer spectrometer
- Infrared intruder system
- Integrated reconnaissance intelligence system
- Infrared interferometer/spectrometer; interim research and intelligence service (u.s. dept. of state); incorporated research institutions for seismology
- An adjustable sized aperture in a camera lens that controls the amount of light reaching the imager. compensates for changing lighting conditions. control may be either manual or automatic, depending on the application and the type of camera. when iris is fixed, a variable electronic shutter can be used instead (ccd ).
- A means of controlling the size of a lens aperture and therefore the amount of light passing through the lens.
- An adjustable opening that limits the amount of light passing through an optical system.
- Iris
- The colored round portion of the eye, situated between the cornea and the lens, and perforated by the pupil. regulates the amount of light entering the eye by adjusting the size of the pupil.
- A coloured ring in the eye, with the pupil at its centre. see illustration at eye in supplement comment: the iris acts like the aperture in a camera shutter, opening and closing to allow more or less light through the pupil into the eye.
- Ring of variable area around the pupil and in front of the lens of the eye. the surface area of the iris adjusts spontaneously to change the amount of light entering the eye.
- Ring of variable area around the pupil and in front of the lens of the eye. the surface area of the iris adjusts spontaneously to change the amount of light entering the eye.3
- A test coach operated on the railway to test the strength of radio signals received via the nrn system.
