- Аннотация: A generalization of the calculation of the formation of ghost images in the course of backward four-photonmixing to the real situation of non-planar spatially limited pumping, which has a Gaussian profile of the fundamentallaser mode, is developed, taking into account the specifics of the formation of ghost images. Computerimages have been obtained that make it possible to estimate the spatial resolution of the systems. A relativelysimple equivalent scheme for describing the process is proposed, which shows that the effect of diffractionin nonlinear systems is similar to its role in ordinary linear optics with a limited aperture. A fiberopticversion of the formation of ghost images is proposed, suitable for the study of hard-to-reach cavities andorgans of the human body, which allow the introduction of a thin fiber bundle there.
