Spatial amplification: an image-processing technique using the selective amplification of spatial frequencies
Spatial amplification: an image-processing technique using the selective amplification of spatial frequencies is a scholarly work, published in 1990 in ''Optics Letters''. The main subjects of the publication include physics, energy, photorefractive effect, lithium niobate, Fourier optics, silicon photonics, computer science, optics, Fourier transform, digital image processing, spatial frequency, spatial analysis, Spatial light modulator, frequency comb, beam, and Spatial filter. A novel technique of processing optical images that authors call spatial amplification is proposed and demonstrated.
