Abstract
Finite transform, matched with free-space optical fields propagation operator and based on beam expansion of plane waves (1D case), has been considered. The spectrum is also band-limited. We demonstrate that this operator is normal, therefore, its eigenfuntions are orthogonal set. We may consider that resulting functions are eigenmodes. We produced the calculations of eigenfunctions where waves propagate at a distance of one wavelength. Elements of some functions are comparable with a half of wavelength. It is allowing to come closer for solving the problem of superresolution in free space.
