- Аннотация: We have applied the measurement reduction technique for the ghost imaging (GI) in fiber optics systems. Ghost images have been reconstructed by numerical simulation of the complete cycle of GI in the basic setup of a multimode fiber endoscope beginning from the propagation of randomly modulated light through a multimode fiber and ending by GI calculation using numerical methods of single-pixel visualization. We have used prior information on the investigated object to obtain high-quality reconstructed ghost images. It is shown that for the number of used patterns of illumination of the object that is much smaller than the number of pixels of the image being reconstructed, the object reconstruction error can be reduced despite the limitation imposed on the number of modes propagating through the optical fiber and forming incoherent radiation. For comparison, we have used several versions of the compressed sensing method and the traditional correlation method. It is demonstrated that the proposed version of the measurement reduction technique applied to multimode fibers shows comparable and often even better results than the traditional correlation method and the compressed sensing method.
