this is not easy though...... n7, 6a ,
R.+-X I guess you need to give a try as sigma indicates the projected width of 1/e squared value of the peak irrdiance in direction cosine space...... for a normally incidence it should be around ~ cosine 85. Good luck !
Hi MANG2004, dVmAMQk.g
DT(Zv2 I am curious about your calculation, too. Plus, the definition of σ refers to 1/e^2 width not the FWHM. Even your calculation/defintion is correct. I have a doubt that it will work when the specualr incident ray angle is not normal......... | 7'yk__m oIL+@}u7 For thsoe who knows it better, please have some input. I am rather curious, too!! Thanks!!
