  In this paper it is shown the performing of an optical transform to state the
scalar diffraction in the formulation of the wavelet transform and the 'wave
equations'. From there, a bridge is build between equations of spherical waves
presented in 1678 by Huygens and the continuous wavelet transform. For such a
purpose, wavelets are introduced that meet the principles of waves and the
properties of wavelets. The following equations are applied in solution to show
a correspondence between the Huygens-Fresnel diffraction and the wavelet
transform.
