Web16 rows · Optical phase conjugation can also be used for holographic imaging and can allow images to be ... WebIt is distinguished from Time Reversal Signal Processing by the fact that phase conjugation uses a holographic or parametric pumping whereas time reversal records and re-emits the signal using transducers. [1] Holographic pumping makes the incident wave interact with a pump wave of the same frequency and records its amplitude-phase distribution.
WebJan 24, 2024 · Optical phase congugation is an effective method for non-linearity and dispersion management in optical fiber (Le et al. 2015; Hu et al. 2016; Watanabe et al. 1996 ). Figure 1 shows two basic methods of phase conjugation in optical fiber set-up. WebCoded aperture imaging (CAI) methods offer multidimensional and multispectral imaging capabilities with minimal resources than what is needed in a lens-based direct imager. In the CAI method, the light diffracted from an object is modulated by a coded mask, and the resulting intensity distribution is recorded. Most of the CAI techniques involve two steps: …
