Wavefront shaping correction makes it possible to image fluorescent particles deep inside scattering tissue. This requires determining a mask be placed in both the excitation and emission paths. Standard approaches select masks by optimizing various metrics, process that capturing prohibitively large number of images. To reduce acquisition cost, iterative phase conjugation techniques use observ...
2014 A mechanical oscillator is used to study phase conjugation : the phase conjugate part of the response of an anharmonic oscillator excited simultaneously by an intense torque and a weak probe torque is calculated. The connections with third order Non Linear Optics susceptibility tensor is presented. Revue Phys. Appl. 17 (1982) 645-648 OCTOBRE 1982, PAGE Classification Physics Abstracts 42.6...
We experimentally demonstrate wavelength-preserving spectral phase conjugation for compensating chromatic dispersion and self-phase modulation in optical fibers. Our implementation is based on a temporal imaging scheme that uses time lenses realized by broadband four-wave mixing in silicon waveguides. By constructing a temporal analog of a 4-f imaging system, we compensate for pulse distortions...
