Does it works now? I enclosed again . It's so weird. if it still not be able to upload, please find it on google by title "Electromagnetic diffraction in optical systems II. Structure of the image field in an aplanatic system" Sorry for the incontinence. Regards.

r_P, theta_P, phi_P, image coordinate theta is open angle of objective lens, theta=arcsin(NA/n). phi is spatial angle at lens coordinate. there is one papar from wolf explain detailly about transfrom from Cartesian coordinate to polar coordinate. Here it is the paper . please find the...

Sorry forgot to put attachment. here it is.

Hi Thank you very much for your post. I tried with small angle. please find the attachment. I also put the formula for PSF. Thanks again for your help,

Hi Andy Resnick, Thanks, Here I've enclosed one attachment, which is according to your suggestion. I = 1/2[I_r + I_t]. I was confused the difference between incoherent light and unpolarized light. I think I = 1/2[I_r + I_t] is more suitable for unpolarized light. do you think...

thanks for your replay. If I understand clearly, your meaning is that doing simply add the two intensity patterns of radial and tangential polarization? which means that in the case of incoherent, it is equivalent to the Superposition of PSF from radial polarized beam and PSF from tangential...

Hi Andy Resnick, Thanks for your replay. 1. for the formula [2], there is one paper from Lars Egil Helseth: "Focusing of atoms with strongly confined light potentials" explained it in detail. 2. normally, the mathematics representation based on vector debye approximation is more suitable...

Sorry for the making you so confused. Thank for your timely replay. I am not familiar for typing math here. so I enclosed pdf format document to here. please find the attachment. Thanks again for your help. Regards.

Thank you very much for your suggestion. I going to try this method. Regards

thanks, I also repeated this two references's results before without any difficulty, using the given mathematics formula, which based on Debey approximation. Now the problem is that for the incoherent light source, I think there is no interaction between each ray, it should be only sum of...

Hi Andy Resnick, I think the both, because in my case, i just use white light source with vary narrow band pass filter. the light is focused by NA=0.6 objective. In second post, I've enclosed one relevant paper which I use to simulate the PSF. I think I going to read the book 'Advanced...

Thanks for your reply. As your suggestion. I've done the simulation for orthogonal polarized light. but there is still side lope, I am wondering, if the incident light is incoherent, I don't think there is side lope emerged, because there is no interference between incoming rays. If I set...

Hi There, Recently, I am working on simulating of Point spread function of high numerical aperture objective lens, according to the Richard and Wolf's mathematics representation, I can do the calculation of PSF, like transverse size or longitudinal size without any difficulty, but this...
