Full-Field Optical Coherence Tomography Based on Hilbert Transform

抄録

Novel image restoration technique suitable for parallel detection in full-field optical coherence tomography (FF-OCT) is introduced. An en-face information of a sample can be demodulated from only two phase-modulated interference images with simple mathematical Hilbert transform process. With the proposed method, a FF-OCT was implemented and its feasibility was verified by taking tomographic images of a biological sample; the wing of the spilota plagicollis fairmaire ex vivo. The system shows the image resolutions of 1.0 µm for the axial direction and 2.2 µm for the lateral direction.
