APPARATUS FOR PARALLEL FOURIER DOMAIN OPTICAL COHERENCE TOMOGRAPHY IMAGING AND IMAGING METHOD USING PARALLEL FOURIER DOMAIN OPTICAL COHERENCE TOMOGRAPHY

摘要

The subject of the invention is a device for imaging objects by Optical Coherence Tomography with parallel Fourier domain detection, containing a light source (LS), a multi-element photo-detector (DET), an interferometer comprising at least one beam splitter (BS), a reference mirror (M1), two optical systems (U1, U2) and an optical system (U3) forming an image on a light detector (DET), characterized in that a device (D1) introducing spatially varying modulation of the phase of light is placed in the path of the light beam between the light source (LS) and the interferometer. The invention also relates to a method of Optical Coherence Tomography with parallel Fourier domain detection using a broadband spectrum light source (LS) and a multi-element photodetector (DET) in which interference images are recorded for different optical frequencies in the range of the light source (LS) used, which are used to create an image reconstructions of the three-dimensional structure of the object (Ob), characterized in that time-variable and spatially varying modulation of the phase of light is employed before the beam emitted by the light source (LS) is split into the reference and object beams, and the obtained interference images are integrated in a complex manner.
