請問各位同行，位置空間光照度與角度空間光照度是怎樣的關(guān)系？它們之間的數(shù)學(xué)轉(zhuǎn)換公式是什么？下面是一個(gè)方形通光管出來的光照度~ ,(u-q]8

What solid angle does that angular pixel represent? NXk~o!D

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. fN1b+d~*6
