CONT

The Bond albedo is the total radiation reflected from an object compared to the total incident radiation from the Sun. The Bond albedo for the Earth is given as 0.29 by de Pater and Lissauer, compared to their value of 0.37 for the geometrical albedo.

OBS

Bond albedo: named for the American astronomer George Bond (1826-1865) ...

OBS

Bond albedo ... is an important measure of a planetary body’s energy balance.

OBS

albedo : A measure of the reflecting power of a nonluminous object, such as a planet, moon, or asteroid. Albedo(from the Latin "albus" for "white") is expressed as the fraction of light and/or other radiation falling on an object [or a surface] that is reflected or scattered back into space; its value ranges from 0, for a perfectly black surface, to 1, for a totally reflective surface.

OBS

Albedo is differentiated into two types, normal albedo and bond albedo.

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

Envisat's ASAR [Advanced Synthetic Aperture Radar] instrument is the first permanent spaceborne radar to incorporate dual-polarisation capabilities-the instrument can transmit and receive signals in either horizontal or vertical polarisation. This Alternating Polarisation(AP) mode can improve the capability of a SAR instrument to classify different types of terrain. Because the reflective properties of a surface are dependant on the polarisation of the incoming radar signal, the use of more than one type of polarisation provides valuable extra information. The ASAR AP mode provides two simultaneous images(or channels) of the same scene taken with different radar polarisation options. Since the radar can transmit and receive in both the horizontal(H) and vertical(V) polarisations, researchers can create image pairs, with possible combinations, HH&VV... HH&HV and VV&VH. A cross-polarisation option employs a channel in which the polarisation signal transmitted by the spacecraft is received on a different polarisation, i. e. transmitted using a horizontal polarisation and received on the vertical for an HV combination, or the reverse for a VH combination.

... the principal light-gathering surface of a reflective telescope.

CONT

The primary mirror is located at the lower end of the telescope tube in a reflector and has its front surface coated with an extremely thin film of metal, such as aluminum. The back of the mirror is usually made of glass, although other materials have been used from time to time. Pyrex (trademark) was the principal glass of choice for many of the older large telescopes, but new technology has led to the development and widespread use of a number of glasses with very low coefficients of expansion.

DEF

Instrument for measuring microwave radiation refracted by a non-smooth surface, such as the sea.

CONT

Instrumentation flown on Seasat included a radar altimeter, a microwave scatterometer for measuring surface wind speed and direction, a scanning multichannel microwave radiometer for sea surface temperature, a visible and infrared radiometer, and the first spaceborne synthetic aperture radar.

CONT

Microwave scatterometer... measures the microwave scattering or reflective properties of surfaces. It is also non-imaging, and is specifically designed to measure backscattering. This requires that it detect more detailed spectral information than imaging radar but has reduced spatial resolution and aerial coverage. The surface is scanned in two or more directions, usually by multiple sensors. The primary application of microwave scatterometers is to measure wind vectors(that is, speed and direction) over the ocean surface. This is based on the principle of ocean ’roughness’ being caused by wind and resulting in a characteristic surface pattern which may be identified by its scattering properties.

DEF

An artificially constructed reservoir for water ... generally ... for decoration, ... surrounding a fountain, or the like.

CONT

The pool is the heart of any successful water feature in the landscape. A well-designed pool can reduce maintenance, complement the active water display and accent the overall landscape composition.... The most commonly used pool depth is 16 in. This seems to be the best depth to achieve a good reflective surface, prevent excessive algae growth, and it will satisfy the requirements of most domestic fountain equipment.

OBS

A pool is apt to be geometric in shape but is not limited to symmetrical or pure geometric forms (circle, square, triangle, trapezoid, etc.).

OBS

The second general type of flat, static water is the pond, which differs from a pool by being designed to appear natural or seminatural.

Optical surface(transmissive or reflective) upon which is ruled a large number of finely spaced grooves; a beam of light impinging upon it is broken into several spectral orders on each side of the central image.

CONT

... spectrographs in astronomy: ... the process of diffraction ... depends on the wave-like properties of the light, and uses a component called a diffraction grating to actually separate the light into its component wavelengths. A diffraction grating consists of a substrate (often made of glass, but stainless steel, plastic, or other materials are sometimes used) onto which are etched very narrowly-spaced lines ... (from several hundred to over one thousand lines etched per millimeter!) A famous physicist ... Henry A. Rowland, was the first person to make high quality diffraction gratings for use in science. ... A transmission grating is a piece of transparent glass or plastic ruled with many finely spaced lines. A grating will break up light into a spectrum just like a prism only it will form many little spectra.

CONT

Un réseau est toute structure périodique qui impose à une onde plane incidente une variation périodique de son amplitude, de sa phase ou des deux à la fois. Dans son principe général de fonctionnement, un réseau diffracte l'onde incidente. [...] Le principe des réseaux a été découvert en 1785 par Rittenhouse [...] Les premiers réseaux furent construits par Young et Fraunhöfer. Le réseau le plus simple est constitué par un ensemble de fentes parallèles réalisant une transmittance en amplitude périodique binaire. Les premiers réseaux d'excellente qualité furent réalisés par Rowland en 1882 (en traçant des traits équidistants sur une lame de verre à l'aide d'une pointe en diamant). Actuellement, on réalise d'excellents réseaux à partir de l'interférence d'ondes planes : ce sont les réseaux holographiques (réseaux sinusoïdaux dont la transmittance est proportionnelle à l'intensité du phénomène d'interférences).

CONT

Pour un réseau donné [...], éclairé par une onde plane [...], la position angulaire [...] des pics principaux dans un ordre donné dépend de la longueur d'onde considérée : un réseau constitue donc un système dispersif (comme un prisme). [...] On met à profit ce pouvoir dispersif pour analyser la lumière émise par une source donnée : c'est le domaine de la spectroscopie.

Many who have used film in a domed theater have come to the conclusion that the domed surface is not the best venue for most motion pictures. For a film to look good on the dome, the dome typically has to have a reflectance of about 30%. Planetarium projectors, especially Digistar, work best with a reflectance above 80%. The darker surface is needed for film to reduce the cross-reflectance that causes a film to look washed-out on a more reflective dome.
