A three-dimensional analogue of an angle, such as that subtended by a cone or formed by planes meeting at a point. It is measured in steradians.
立体角
Example sentencesExamples
The rest of it is some geometry, and knowledge about solid angles, which is not really interesting and hard to demonstrate without boring figures.
The solid angle in question is only p / 4 steradian, one-sixteenth of the entire sky.
Gradually, we acquire independence in one cone after another until we have covered the entire solid angle of all the cones that compose it…
Equation 1 already includes a cos term to compensate for the solid angle, so adding a solid-angle term produces a result that is two times larger than the result in equation 2.
The imaging system objective collects the unscattered incident light and the scattered light that falls within the solid angle defined by its numerical aperture.
