Translations

point source

A celestial object whose angular extent is too small to be measured.

point source

[′pȯint ‚sȯrs] (civil engineering) A municipal or industrial wastewater discharge through a discrete pipe or channel. (physics) A source of radiation having definite position but no extension in space; this is an ideal which is a good approximation for distances from the source sufficiently large compared to the dimensions of the source.

point source

A light source whose dimensions are insignificant compared with the distance at which it is used; e.g., a fluorescent lamp is a point source when viewed from a large distance but a line source when viewed close to the source.

point source

(poynt sōrs), In photometry, a small source of light that is regarded as a geometric point from which light emanates in straight lines in all directions.

point source

A geographically limited, fixed location from which a disease or an environmental pollutant spreads.

source, point

A source whose dimensions are sufficiently small to cause a radiation with a high degree of coherence. If the point source is situated on the axis of an optical system it gives rise to an axial ray and it is referred to as an axial point source. See coherent sources; axial ray.
