solid angle in a sentence

Examples

1. In the ideal case each objective lens can collect light from a solid angle of \ Omega = 2 \ pi.
2. This can be modeled as a point spread function ( PSF ) weighted within a solid angle larger than the pixel.
3. In case of optical instruments or sensors it is a solid angle through which a detector is sensitive to electromagnetic radiation.
4. The anholonomy induced by a complete circuit of latitude is proportional to the solid angle subtended by that circle of latitude.
5. Next, emitting area must be converted into a projected area and the solid angle; this product is often called the etendue.
6. Indeed, as viewed from any point on Earth, both objects have approximately the same solid angle as well as apparent size.
7. So, with two objective lenses one can collect from every direction ( solid angle \ Omega = 4 \ pi ).
8. The detector solid angle has to be closed, but the thick sample can take more current without heating, which decreases sample degradation.
9. Therefore, a detector system with large solid angle as well as high depth resolution may enable corrections for the kinematic energy shift.
10. This is because it is defined per unit solid angle, the definition of which refers to the area of the detecting surface.
