    Abstract: There is set forth in one embodiment an apparatus and method for imparting a phase shift to an input waveform for output of a converted waveform. In one embodiment, a phase shift can be provided by four wave mixing of an input waveform and a pump pulse. In one embodiment, there is set forth an apparatus and method for generating a high resolution time domain representation of an input waveform comprising: dispersing the input waveform to generate a dispersed input waveform; subjecting the dispersed input waveform to four wave mixing by combining the dispersed input waveform with a dispersed pump pulse to generate a converted waveform; and presenting the converted waveform to a detector unit. In one embodiment a detector unit can include a spectrometer (spectrum analyzer) for recording of the converted waveform and output of a record representing the input waveform.

    Abstract: The invention relates to a wavefront analysis method involving multilateral interferometry with frequency difference. According to the invention, a diffraction grating (GR) with two-dimensional meshing is placed on the path of the beam to be analysed and at least two interferograms with at least two different colours are processed, each interferogram being obtained in a plane (P s ) from two sub-beams (R1, R2) with different diffraction orders. The invention can be used to analyse and correct sheared wavefronts (S).

    Abstract: An incident optical signal is captured by an array of apertures and directed to pairs of fibers, each pair having a delay fiber with a unique length and a no-delay fiber. Each pair of fibers further has a unique transmission characteristic. Time interpolation is then performed using the transmission characteristic curve for each delay fiber and the duration from the time the optical signal arrives over the no-delay fibers and the time the signal arrives over the delay fibers to determine the wavelength. In a second embodiment, each pair of delay and no-delay fibers is replaced by a fiber splitter which directs light into a no-delay fiber and a delay fiber that have been split from the input of the splitter. In a third embodiment, two fiber splitters are used in place of the pairs of fibers. Each splitter has a number of branches for receiving light and an output end for guiding light onto the photodetectors. The propagation time of the delay optical signal, as compared against the no-delay signal, and other factors such as the length of the individual fiber and the transmission characteristics, are used to determine the wavelength.
