this is not easy though...... Dxxm="FQZ V>
bCKtf& 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, 9I/N4sou MxGW(p 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......... hG:|9Sol, VQ{fne< For thsoe who knows it better, please have some input. I am rather curious, too!! Thanks!!
Hi, hopebox, -S+zmo8 XS BA$y Thanks for your reply. Really like those words “guess”, “doubt”… 0C*7K?/ KK%M~Y+tU' For your curiosity, have good luck! X~i<g?] i2^>vYCsl MANG2004 pU7lnS[
