A method and system for use in reconstruction and retrieval of phase information associated with a two-dimensional diffractive response are presented. The method comprising: providing () input data indicative of one or more diffractive patterns corresponding to diffractive responses from one or more objects (). Dividing () said input data into a plurality of one-dimensional slices and determining () one-dimensional phase data for at least some of said one-dimensional slices. Tailoring () the reconstructed phase data of said one-dimensional slices to form a two-dimensional phase solution. The two-dimensional phase solution is defined by phase shifts of said reconstructed one-dimensional phase data of said one-dimensional slices. The two-dimensional phase solution thus enables obtaining two-dimensional reconstructed phase data suitable for reconstruction of image data ().

System and method for phase retrieval in lensless imaging

A method and system () are presented for producing exciting radiation (P') to be used in producing an output coherent anti-stokes Raman scattering (CARS) signal of a medium (). An input spectral phase coherent optical pulse (P), carrying a pump, a Stokes and a probe photon, is optically processed by adjusting spectral phase and polarization of wavelength components of the input pulse to produce a unitary optical exciting pulse (P&#x2032;) that carries the pump photon, the Stokes photon and multiple probe photons and is capable of inducing interference between contributions from at least some of vibrational levels in the CARS signal.

Coherently controlled nonlinear raman spectroscopy

A method and system are presented for producing an output coherent anti-stokes Raman scattering (CARS) signal of a medium. The method comprises generation of a unitary optical excitation pulse that carries a pump photon, a Stokes photon and a probe photon; and inducing a CARS process in the medium by exciting the medium by the at least one such unitary optical excitation pulse.
