1. An imaging apparatus, said imaging apparatus comprising:

  • at least one source of coherent radiation outputting a plurality of wavelengths illuminating an object creating a plurality of speckle patterns each corresponding to the plurality of wavelengths;

    at least one sensor at a location relative to said object to determine the intensity of the speckle pattern for each of the plurality of wavelengths;

    a processor receiving information from said at least one sensor, said processor having means for constructing at least one autocorrelation of said object from said intensities of said speckle pattern;

    a controller for controlling the at least one source of coherent radiation creating a projected reference point; and

    said processor further comprising means for executing a regional image selection technique to construct a representation of said object utilizing said projected reference point and said autocorrelation.
