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.

Infrared, английский
- Infrared. the electromagnetic radiation with wavelengths longer than about 700 nm and not visible to the human eye.
- `инфракрасный
- Инфракрасный
- Industries, incorporated фирма «инфраред индастриз, ин- корпорейтед»
- That portion of the electromagnetic spectrum just below visible light; infrared radiation has a wavelength from 800 nm to about 1mm. fiber-optic transmission is predominantly in the near-infrared region, about 800 to 1600 nm.
- Light wavelengths extending from 770 nm on
- Electromagnetic energy usually defined as heat in the invisible part of the
- A portion of the electromagnetic spectrum to which the human eye is not sensitive but which can be used with infrared film and filter to record images of unusual tonal balance. infrared rays produce heat when they strike objects. see: heat filter.
- Electromagnetic radiation with wavelengths longer than visible light, but shorter than microwave radiation.
- That region of the electromagnetic spectrum at wavelengths immediately above the visible spectrum; the heat in this region of the spectrum which is generated by a light source usually is undesirable (since it represents a loss in efficiency), but such heat is used in industrial applications for drying, baking a surface, etc.
- Invisible electromagnetic radiation between light and radio waves
- Beyond infrared, referring to radiation with frequency lower than, and wavelength greater than, that of the color red. see infrared radiation.
Infrared (adj), английский
Having a frequency in the electromagnetic spectrum in the range just below that of red light.
Infrared (ir), английский
- Electromagnetic radiation which occupies the band from 0.7 microns to 100 microns. infrared radiation is between the visible spectrum and microwave radiation. emission of energy as electromagnetic waves in the portion of the spectrum just beyond the limit
- Low frequency light below the visible spectrum. infrared is used in surveillance cameras to provide a light source to record images in dark and zero light conditions.
- Infrared (ir) cameras feature built-in illuminators that project infrared light, which is nearly invisible to the human eye but very visible to ir surveillance cameras. this technology allows you to capture crystal clear, black and white video of suspects who feel protected by complete darkness. ir cameras are very effective in covering targeted areas with little or no light, ranging from exterior parking areas and entryways, to interior rooms requiring 24 hour surveillance. for coverage of wider areas, consider adding an additional external infrared illuminator.
- Light with wavelengths longer than 700nm and shorter than about 1mm, invisible to the human eye, which we can feel as heat. glass optical fibers transmit infrared signals at 700 to about 1650nm in the infrared.
Infrared (ir) spectroscopy, английский
A technique in which infrared light is passed through matter and some of the light is absorbed by inciting molecular vibration. the difference between the incident and the emitted radiation reveals structural and functional data about the molecule.
Infrared acquisition (aid), английский
Средство обнаружения по ик-излу- чению
Infrared active homing, английский
Активное ик-самонаведение 312
Infrared alternate head, английский
Резервная ик-головка (самонаведения)
Infrared amplification by- stimulated, английский
Emission of radiation иразер, квантовомеханический генератор [усилитель] ик-диапазона
Infrared analysis, английский
A form of absorption spectroscopy that identifies organic functional groups present in a used oil sample by measuring their light absorption at specific infrared wavelengths; absorbance is proportional to concentration. the test can indicate additive depletion, the presence of water, hydrocarbon contamination of a synthetic lubricant, oxidation, nitration, and glycol contamination from coolant. fourier transform infrared (ftir) permits the generation of complex curves from digitally represented data.
Infrared and thermal testing, английский
Nondestructive testing that uses heat diffusion and infrared radiation as interrogating energy.
Infrared astronomy explorer, английский
•спутник серии «эксплорер» для астрономических исследований в ик- части спектра
Infrared atmospheric sounding interferometer, английский
Infrared bomb, английский
Бомба с ик-си- стемой самонаведения
Infrared brazing, английский
Infrared connection, английский
A way to wirelessly connect computers and devices, using infrared light to send information.
Infrared counter-countermea- sure, английский
Борь`ба с ик-противодействием
Infrared countermeasure, английский
- Ик-про- тиводействие
- Ик- •противодействие
Infrared data association, английский
- Ассоциация по инфракрасной технологии передачи данных
- The industry organization of computer, component, and telecommunications vendors who have established the standards for infrared communication between computers and peripheral devices such as printers.
Infrared device, английский
A computer, or a computer peripheral such as a printer, that can communicate using infrared light.
Infrared diode, английский
Infrared drying, английский
Drying by use of infrared lamps to decrease drying time.
