solid angle in a sentence

Examples

1. Therefore, its radiance ( power per unit solid angle per unit projected source area ) is the same.
2. By the same argument, the maximum solid angle that can be subtended at any point is 4 sr.
3. The BRDF has units sr  " 1, with steradians ( sr ) being a unit of solid angle.
4. The name of this type of microscopy is derived from the maximal possible solid angle for excitation and detection.
5. The solid angle \ Omega that is used for illumination and detection is increased and approaches the ideal case.
6. The anholonomy is still proportional to the solid angle subtended by the path, which may now be quite irregular.
7. Instead of the solid angle, the momentum transfer may be used as the independent variable of differential cross sections.
8. When implementing the above equation care must be taken with the atan function to avoid negative or incorrect solid angles.
9. The units of the spectral radiance are seen to be energy / time / area / solid angle / frequency.
10. :Intensity is the energy flux emitted per unit solid angle, so this will be uc / ( 4 pi ).
