What solid angle does that angular pixel represent? &;,,H< p `(+o=HsD 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. 1axQ)},o@p How is Radiant Intensity Defined u?Tpi[
