8.4 DOEs for analysis of the transverse modes of light fields
Very close to the problem of generating light fields is the problem of their analysis, in particular, the expansion in some orthonormal basis. Whilst the spectral decomposition can be performed using a spherical lens, there are no appropriate instruments for the other bases in classical optics. Thus, the formation of the DOE performing an expansion in the given orthogonal functions is an important task. These devices are represented by the DOEs [4,20], matched with a variety of orthogonal functions. These elements can be used for:
– individual excitation, measurement and detection of coherent radiation modes (Bessel mode, GL, GH);
– analysis of the wavefront and recovery phase (Zernike ...
