Abstract (en)

[origin: WO0055572A1] An in-focus image of an information-bearing region within and/or on a substance is discriminated from an out-of focus image so as to reduce errors in image information of the substance by producing a probe beam and a reference beam from a wideband point source (90a), producing antisymmetric spatial properties in the reference beam (83), converting the probe beam (81b) to a beam focused to a line in the region, producing antisymmetric spatial properties in the in-focus return probe beam.
