Gain_22

iadpython.sphere.Gain_22(RS, TS, URU, tdiffuse)

Two sphere gain in T sphere for light starting in T sphere.

Similarly, when the light starts in the second sphere, the gain for light on the detector in the second sphere \(G_{22}\) is found by switching all primed variables to unprimed. Thus \(G_{21}(r_s,t_s)\) is

\[G_{22}(r_s,t_s) =\frac{G'(r_s)}{1-a_s a_s'r_w r_w'(1-a_e)(1-a_e')G(r_s)G'(r_s)t_s^2}\]
