# Improvement of optical image by measurement reduction technique at parametric multiplexing. (arXiv:1812.02589v1 [quant-ph])

In the process of parametric optical image amplification, images are formed
at new frequencies in addition to the amplified original image. We show that
the parametric multiplexing of optical images can be used to produce an image
with improved quality. As an example, we study the parametric amplification of
an optical image at low-frequency pumping in which multiplexed optical images
