Cassegrain yansıtıcı temel bir içbükey ayna ile ikincil bir dışbükey aynanın birlikteliğidir ve çoğunlukla optik teleskoplarda ve radyo antenlerinde kullanılır
(Askeri) NAMLU MUAYENE AYNASI: Bir top veya tüfek namlusunun içini veya atım yatağını muayeneye yarayan cihaz. Namlu muayene aynası, bir çerçeve üzerine takılı bir ayna ile, atım yatağına takılan ve namlu içinin görünmesine yarayan bir ayna ve borudan ibarettir
(Askeri) ŞAŞIRTMA REFLEKTÖRÜ: Karıştırma amacıyla eko yaratmakta kullanılan bir elektromanyetik radyasyon reflektörü. Radar şaşırtma reflektörleri hail levha, hail şerit ve köşe reflektörleri gibi cihazları içermektedir
(Askeri) KÖŞELİ REFLEKTÖR: 1. Birbirini dik olarak kesen madeni levha veya tabakalardan ibaret bir cihaz. Bu cihaz, bir radar hedefi veya işareti olarak faaliyet gösterecek şekilde tasarlanmıştır.2. Radar değerlendirmesinde, düz satıhtan gelen çoklu yansımalar vasıtasıyla hedefin tahmin edilen ölçülerinden daha büyük radar yansıması oluşturan bir nesne
A device used to direct the light from a source through the process of reflection
A telescope that uses as its primary optical element a mirror Nearly all large telescopes in use today by amateur and professional astronomers are reflecting telescopes
{i} person or thing which reflects; telescope that uses concave mirrors to focus; material used to inhibit the escape of neutrons from the core of a reactor (Physics)
This is the part of the Earth Station Antenna which "bounces" the RF signal into the feed Most typical reflectors are parabolic dishes, and are usually referred to as dishes or antennas Originally antennas were made large, on the order of 32 meters in diameter, but there is a trend toward smaller and smaller diameter antennas Since most operating parameters for Earth Stations are functions of the diameter of the antenna, it is the most important parameter
Any material or surface that reflects light Reflectors are often used in photography to soften the effect of the main light or to bounce illumination into subjects shadows
The part of a light fixture that shrouds the lamp and redirects some of the light emitted from the lamp
An optical device to reflect light PHOTO-OPTIC reflector lamps utilize ellipsoidal (converging light rays) or parabolic (collimating light rays) reflectors Dichroic coated reflectors are designed to reflect visible light and pass through unwanted infrared wavelengths
Something having a polished surface for reflecting light or heat, as a mirror, a speculum, etc
optical telescope consisting of a large concave mirror that produces an image that is magnified by the eyepiece; "Isaac Newton invented the reflecting telescope in 1668"
A surface, usually a rock or SEDIMENT layer, that strongly reflects seismic (sound) waves
A file server whose purpose is to receive packets from a source site and forward it to other sites
An object used as an identifiable artificial landmark which causes reflected radiation to return along paths parallel to those of their corresponding incident rays
1)A reflective surface, such as a piece of white cardboard, that can be positioned to redirect light, especially into shadow areas Also called a flat 2) A reflective surface, often bowl-shaped, that is placed behind a lamp to direct more light form the lamp toward the subject
A reflector is a type of telescope which uses a mirror that is shaped like a ball
A device used to redirect the light flow from a source by bouncing it off the surface
An interface between materials of different elastic properties that reflects seismic waves
This type of telescope uses a mirror to focus the image instead of a lens See Telescope Types
Any surface from which light can be reflected In particular white cardboard or similar material, used to reflect light from a main source into shadow areas
1 In general, any object that reflects incident energy; usually it is a device designed for specific reflection characteristics See retroreflector, corner reflector, parabolic reflector, radar reflector
In an antenna, one or more conducting elements or surfaces that reflect incident radiant energy (188)
(sol) A device that can be used to reflect and focus SOLAR RADIATION F - reflecteur S - reflector
1 ) A reflective surface, such as a piece of white cardboard, that can be positioned to redirect length, especially into shadow areas Also called a flat 2 ) A reflective surface, often bowl-shaped, that is placed behind a lamp to direct more light from the lamp toward the subject
A reflector is a small piece of specially patterned glass or plastic which is fitted to the back of a bicycle or car or to a post beside the road, and which glows when light shines on it
A device designed to reflect radar waves well in order to make it clearly visible on radar screens. Radar reflectors can be installed for example in boats or signal buoys
The Cassegrain reflector is a combination of two coaxial reflectors used in Cassegrain telescopes and radio antennas. First developed in 1672 by Laurent Cassegrain, this reflector is a combination of a primary concave mirror and a secondary convex mirror, both aligned symmetrically about the optical axis
