This theory was initially implemented in Lentz's another research when he calculated ratios of Bessel function necessary for [[Mie scattering]]. He demonstrated that the algorithm uses a technique involving the evaluation continued fractions that starts from the beginning and not at the tail. In addition, that continued fraction representations for both ratios of Bessel functions and spherical Bessel functions of consecutive order can be presented with the Lentz algorithm.<ref>{{Cite journal|last=Lentz|first=William J.|date=1976-03-01|title=Generating Bessel functions in Mie scattering calculations using continued fractions|url=http://dx.doi.org/10.1364/ao.15.000668|journal=Applied Optics|volume=15|issue=3|pages=668|doi=10.1364/ao.15.000668|issn=0003-6935}}</ref> The algorithm suggested that it is possible to terminate the evaluation of continued fractions when <math>|f_j-f_({j-1)} |</math> is relatively small.<ref>{{Cite journal|last=Masmoudi|first=Atef|last2=Bouhlel|first2=Med Salim|last3=Puech|first3=William|date=2012-03|title=Image encryption using chaotic standard map and engle continued fractions map|url=http://dx.doi.org/10.1109/setit.2012.6481959|journal=2012 6th International Conference on Sciences of Electronics, Technologies of Information and Telecommunications (SETIT)|publisher=IEEE|doi=10.1109/setit.2012.6481959}}</ref>
