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.

    摘要: The Fourier transforming properties of simple lenses and related optical elements is well known and heavily used in a branch of engineering known as “Fourier Optics.” Classical Fourier Optics allows for relatively easy, inexpensive, flexible signal processing of images by using lenses or other means to take two-dimensional Fourier transforms of an optical wavefront and using a translucent plate or similar means in this location to introduce an optical transfer function operation on the optical wavefront. The image processing possibilities have historically been limited to transfer functions that mathematically are “positive-definite,” i.e. those which affect only amplitude and do not introduce varying phase relationships. The method of this invention uses Fractional Fourier transform properties of lenses or other elements or optical environments to introduce one or more positive-definite optical transfer functions at various locations outside the Fourier plane so as to realize or closely approximate arbitrary non-positive-definite transfer functions. Designs can be straightforwardly obtained by methods of approximation. The invention provides for the application of these methods to create single and multiple channel controllable optical processors which may be used for image or other types of computation, including computation with complex-valued arithmetic, visual color, and wide-spectrum optical signals. The methods can be extended for other arrangements, such as phase-shifting filter elements and non-quadratic graded-index materials (which do not naturally invoke the Fractional Fourier transform operation). Applications of the invention include integrated optics, optical computing systems, particle beam systems, radiation accelerators, astronomical observation methods, and controllable lens systems.
