“…2 1. Another promising method would be to consider the triangular interferometer of Hariharan and Sen (22,23). If one instead would resort to electronics, the wave-front differential operator could be implemented by operational amplifiers, since these can easily perform a derivative operation (see ref.…”

The wave departures from sphericity known as Seidel's primary-or third-order aberrations are represented by a differential operator that modifies the diffraction-limited image. We show that the complex amplitude at any point over the aberrant image can be obtained from certain terms of the Taylor series expansion of the diffraction limited image. This approach allows us to describe the propagation of an aberrant wave front in terms of its aberration coefficients. Furthermore, it can also be applied to implement an optical or an electronic procedure for simulating aberrant images.Nous representons par un opkrateur diffkrentiel, modifiant I'image diffractionnelle idkale, I'effet sur celle-ci des Ccarts ondulatoires relativement a la sphkre, connus sous le nom d'aberrations de Seidel primaires, ou du troisikme ordre. Nous dCmontrons qu'en tout point de I'image entachke d'aberrations I'amplitude complexe peut Ctre obtenue ii partir de certains termes du dkveloppement de Taylor de I'image diffractionnelle idkale. Suivant cette voie il devient possible de dkcrire la propagation d'un front d'onde aberrant en termes de ses coefficients d'aberration. De plus on peut la mettre en oeuvre via des moyens optiques ou klectroniques capables de simuler des images entachkes d'aberrations.

“…The fluorescent method for the determination of uranium has been reviewed by Markov with 13 references (305). A new' fluorometer for uranium determination with a beam splitter on the excitation is described by Haran (189). New equipment for making fluorescent melts has been designed by Lew'andowski (282).…”
