MULTIVARIATE FLUORESCENCE IMAGING OF GEL ON NYLON-66 PRODUCTION PACK SCREENS

Fluorescence microscopy is an established technique for qualitative an d quantitative surface imaging. Because many ''real world'' surfaces o f interest are optically rough (vertical variations on the order of 10 0 mu m or more) it is of great interest to minimize the amount of spec tral information lost because of depth-of-focus variations. Multivaria te statistics on normalized spectra provide an ideal method for extrac ting information from such data. The following study examines nylon 66 gel on production pack screens via multivariate fluorescence imaging.
