[citation needed]), Conservation of etendue can be derived in different contexts, such as from optical first principles, from Hamiltonian optics or from the second law of thermodynamics. You can also try the grid of 16 letters.  |  Because angles, solid angles, and refractive indices are dimensionless quantities, etendue has units of area (given by dS). If both surfaces dΣ and dS are immersed in air (or in vacuum), n=1 and the expression above for the etendue may be written as.

These definitions must be applied for infinitesimally small "elements" of area and solid angle, which must then be summed over both the source and the diaphragm as shown below. Recherche - Définition . The same result is also valid for the case of a reflection at a surface dS, in which case nΣ=nS and θΣ=θS. Etendue can then remain constant or it can increase as light propagates through an optic, but it cannot decrease. To make squares disappear and save space for other squares you have to assemble English words (left, right, up, down) from the falling squares. Etendue or étendue ("ay-ten-due") is a property of pencils of rays in an optical system, which characterizes how "spread out" light is in area and angle. Définition ou synonyme.

Information and translations of etendue in the most comprehensive … The directions of the incoming and refracted light are contained in a plane making an angle φ to the z axis, defining these directions in a spherical coordinate system. 3. These expressions result in showing that etendue is conserved as light propagates in free space. The etendue of this light crossing dS is defined in 2D as. Nombre de lettres. To compute the etendue of the system, one must consider the contribution of each point on the surface of the light source as they cast rays to each point on the receiver.[3]. 5. L'Utilisation de ces marques sur motscroisés.fr est uniquement à des fins d'information. Most English definitions are provided by WordNet . What does etendue mean? It is then also conserved as light travels through optical systems where it suffers perfect reflections or refractions. Pas de bonne réponse? Accordingly, the etendue of the light crossing dS coming from dΣ is given by: where is the solid angle defined by area dΣ. As light travels through an ideal optical system, both the etendue and the energy flux are conserved. Throughput and AΩ product are especially used in radiometry and radiative transfer where it is related to the view factor (or shape factor).

Now, if a large surface S is crossed by (or emits) light also confined to a cone of angle α, the etendue of the light crossing S is, The limit on maximum concentration (shown) is an optic with an entrance aperture, S, in air (nI=1) collecting light within a solid angle of angle 2α and sending it to a smaller area receiver Σ immersed in a medium of refractive index n, whose points are illuminated within a solid angle of angle 2β. 4) Étendre la clause d'un contrat, les termes d'un arrêt, etc. It may also be seen as a volume in phase space. Aide mots fléchés et mots croisés. Voir les synonymes d'Étendu classés par nombre de lettres. Integration on dΣ and dS results in which allows the etendue between two surfaces to be obtained from the view factors between those surfaces, as provided in a list of view factors for specific geometry cases or in several heat transfer textbooks. From the source point of view, it is the area of the source times the solid angle the system's entrance pupil subtends as seen from the source.

In the context of Hamiltonian optics, at a point in space, a light ray may be completely defined by a point P=(x,y,z), a unit Euclidean vector indicating its direction and the refractive index n at point P. The optical momentum of the ray at that point is defined by. For a given angular aperture, α, of the incoming light, this concentration will be maximum for the maximum value of β, that is β=π/2.

With these definitions, Snell's law of refraction can be written as, where both sides of the equation were also multiplied by dφ which does not change on refraction. The conservation of etendue discussed above applies to the case of light propagation in free space, or more generally, in a medium in which the refractive index is constant.  |  The etendue is related to the Lagrange invariant and the optical invariant, which share the property of being constant in an ideal optical system.
