CONT

Retroreflective fabrics are necessary to extend the same level of protection at night that fluorescent fabrics provide during daylight. Retroreflective fabric works like a mirror, reflecting light back to its source.

Record 3 2017-04-26

English

Subject field(s)
  • Crustaceans
CONT

Square array of mirrored plugs in the reflecting compound eye of the lobster Palinurus vulgaris is visible in this micrograph. Mirrors of the square plugs act as corner reflectors, which have the property of behaving like a single mirror always at right angles to the incident ray.

French

Domaine(s)
  • Crustacés
CONT

La mosaïque carrée des tampons réflecteurs dans l'œil composé de la langouste Palinurus vulgaris est visible sur cette micrographie. Les miroirs ont un effet analogue à celui d'un jeu de miroirs orthogonaux qui guident la lumière vers la rétine.

Record 4 2015-04-08

English

Subject field(s)
  • Optical Glass
  • Photography
CONT

Mirror lenses have no diaphragm; light transmission is regulated by filters built into the rear of the lens, or by varying the shutter speed. Because of its reflecting design and the different types of mirrored surfaces used to transmit the light, most mirror lenses will transmit up to a full f-stop less light to the film plane than their rated speed.

French

Domaine(s)
  • Verres d'optique
  • Photographie
CONT

L'objectif catadioptrique [...] consiste essentiellement en une combinaison de lentilles et de miroirs d'où la lumière est projetée par réfraction d'une lentille sur un réflecteur interne, pour être ensuite projetée vers le plan focal, selon une espèce de trajectoire que l'on pourrait décrire comme étant en forme de zigzag.

CONT

L'un des désavantages (typiques) des objectifs catadioptriques est l'absence de diaphragme.

Subject field(s)
  • Building Insulation and Acoustical Design
CONT

A shell-shaped or concave recess of reflecting material should be built behind the performers to act as a mirror to throw out the sound on a more or less plane wave-front... If this reflector consists of wood sheathing against the wall, it is well to leave a space by supporting the wood on studs away from the wall.

Record 7 2005-01-24

English

Subject field(s)
  • Radar, Radio Guidance and Goniometry
  • Spacecraft
  • Remote Sensing
DEF

Remote sensing systems that build up an image by scanning from side to side in a direction that is at right angles to the sensors direction of movement[;] this scanning from side to side is achieved through electromechanical mechanisms which change the direction of view of the sensor.

CONT

Spatial imaging is achieved using the push-broom principle: the across-track scanning is performed electronically and the along-track scanning is made thanks to the satellite motion.

OBS

Sensors aboard the Landsat satellites were built in a "whisk broom"(across track) configuration. In a whisk broom sensor, a mirror scans across the satellite's path, reflecting light into a single detector which collects data one pixel at a time. The moving parts make this type of sensor expensive and more prone to wearing out.

OBS

across-track scanning: term officially approved by the RADARSAT-2 Terminology Approval Group (RTAG).

Key term(s)
  • cross-track scanning
  • across track scanning

French

Domaine(s)
  • Radar, radioguidage et radiogoniométrie
  • Engins spatiaux
  • Télédétection
DEF

Scannage effectué par défilement du champ de visée instantané perpendiculairement à la trace de la plate-forme d'observation sur le sol.

OBS

Le «scannage transversal» peut être réalisé par des moyens mécaniques ou électroniques.

Record 8 2003-01-06

English

Subject field(s)
  • The Sun (Astronomy)
CONT

Sun glint occurs when the ocean acts like a mirror, directly reflecting the sunlight to the imager of the satellite. Therefore, sun glint, like an image in a mirror, provides two kinds of information. It can help to locate the position of the sun, and its varying brightness and clarity provide information about the reflecting surface. In this way, sun glint is used to study ocean surface activity.

Record 9 2000-02-18

English

Subject field(s)
  • Optics
DEF

An instrument containing mirror reflecting surfaces which produce a changing pattern when viewed against light.

CONT

A slight turn of a kaleidoscope when you’re looking through it and you get a different view of things. The image changes. If you turn the kaleidoscope a great deal, the image changes substantially or even completely. If you turn the kaleidoscope only slightly, however, the image changes only slightly, being built partly upon that at which you were looking initially.

English

Subject field(s)
  • Aeroindustry
  • Radar, Radio Guidance and Goniometry
CONT

Detection relies entirely on echoes returned by the main rotor blades which do yield a significant Doppler effect. Experience has shown that rotor blades, whether metal or plastic, behave like mirrors in terms of reflecting electromagnetic radiation. In other words, a blade will only give a usable return to the transmitter location if it is perpendicular to line connecting blade and transmitter. At the receiver, a series of return pulses can be detected, each corresponding to the passage of a blade. By analogy with the illumination of a rotating mirror, this pulsed return pattern is known as "blade flash".

French

Domaine(s)
  • Constructions aéronautiques
  • Radar, radioguidage et radiogoniométrie
CONT

La détection repose entièrement sur les échos renvoyés par les pales du rotor principal qui, eux, présentent un effet Doppler important. L'expérience a montré que les pales, métalliques ou plastiques, se comportent vis-à-vis du rayonnement électromagnétique comme des miroirs. En d'autres termes, elles ne réfléchissent l'émission radar que si elles sont perpendiculaires à celle-ci. A la réception, on enregistre donc une série de retours de caractères impulsionnels, chacun correspondant au passage d'une pale. Par analogie avec l'illumination d'un miroir tournant, on appelle "éclairs de pale" ces retours impulsionnels.
