WebApr 10, 2024 · The well-known Fourier slice theorem is extended to incoherent tomographic imaging, which states that a detected image under an ideal aperture corresponds to a central slice in the 3D object spectrum, so the spectrum coverage can be accomplished based on the motion-free aperture modulation. WebASE creates serious problems in any laser with high gain and/or large size. In this case, a mechanism to absorb or extract the incoherent ASE must be provided, otherwise the excitation of the gain medium will be depleted by the incoherent ASE rather than by the desired coherent laser radiation.
