J. Lancis et al., ACHROMATIC WHITE-LIGHT SELF-IMAGING PHENOMENON - AN APPROACH USING THE WIGNER DISTRIBUTION FUNCTION, J. mod. opt., 42(2), 1995, pp. 425-434
The propagation of polychromatic spatially coherent light through an o
ptical system, developed for achromatizing Fresnel diffraction pattern
s, is discussed using the Wigner distribution function. This approach
is applied for obtaining achromatic self-images. The residual chromati
c aberration is analysed, and some experimental results are shown.
