http://listserv.acsu.buffalo.edu/cgi-bin/wa?S1=confocal Dear all, I appreciate if you help me to figure out how I can calculate the SNR from the data that I obtain by imaging the fluorescent beads in different depths. Thanks Sarah |

http://listserv.acsu.buffalo.edu/cgi-bin/wa?S1=confocal Maybe I am misunderstanding your question, but if you are interested in SNR why do you need beads? Cannot you just measure SNR for a comparable signal coming from something larger than a bead?

http://listserv.acsu.buffalo.edu/cgi-bin/wa?S1=confocal Dear Mike, Yes,You are right.The reseaon that I use beads is I have embeded beads inside my sample so by measuring them in the different depths I can have a good scale of being in the focal plane and then measuring the SNR. regards sarah On Thu, Apr 10, 2008 at 5:30 PM, MODEL, MICHAEL <[hidden email]> wrote: > Search the CONFOCAL archive at > http://listserv.acsu.buffalo.edu/cgi-bin/wa?S1=confocal > > Maybe I am misunderstanding your question, but if you are interested in > SNR why do you need beads?

http://listserv.acsu.buffalo.edu/cgi-bin/wa?S1=confocal Dear Tom, So,do you think it is a good approximation of SNR if I find the ratio of the max photon count to the min one of the PSF graph?
