Title:
INTERFERENCE APPARATUS AND METHOD AND PROBE
Document Type and Number:
WIPO Patent Application WO2006054116
Kind Code:
A3
Abstract:
An optical interference apparatus for carrying out Fourier domain optical coherence tomography including means to provide multiple beams whereby interferograms are recorded simultaneously for a plurality of different focal depths within a substance to be examined, each interferogram being provided by one of the multiple beams. Means is provided for combining images derived from said interferograms for a plurality of different focal depths, whereby a single image may be constructed with an increased depth of field. The axial spacing of the foci is calculated to take into account the Rayleigh range of the focal waist in the substance to be examined.
