位置空间光照度与角度空间光照度

请问各位同行,位置空间光照度与角度空间光照度是怎样的关系?它们之间的数学转换公式是什么?下面是一个方形通光管出来的光照度~ Fds 11 /c7

What solid angle does that angular pixel represent? $s/E } X

To answer that question we project out from the local axis of the detector to construct a sphere some long distance away from the detector, centered on the detector. We then (conceptually) fire rays from this point at x, y angles of (5, 40), (5, 41), (6, 41), and (6, 40). Now we know that patch of area, we can compute the solid angle subtended by that angular pixel. -Lh7!d
