Procedia Engineering, 140, 140-143. doi:10.1016/j.proeng.2015.07.358 | Series/Report no.: | Procedia Engineering | Abstract: | Spectral domain optical coherence tomography (SD-OCT) with dual-balanced detection (DBD) for signal-to-noise ratio (SNR) enhancement is developed. The dual-balanced detection in the SD-OCT system inherently achieves two-fold increase of the interested signal amplitude, minimizes the common background noise and suppresses artifacts by combining two phase-opposed interferometric spectra obtained simultaneously in comparison to unbalanced detection configuration, resulting in a significant SNR increase and dc elimination performance. Two interferometric spectrum were captured using a dual-line CCD through the same spectrometer optics. This new design is of lower cost compared with the dual CCD design. The feasibility and validity of this SD-OCT system with dual-balanced detection are demonstrated by experimental measurement of a 95% reflector. | URI: | https://hdl.handle.net/10356/89402 http://hdl.handle.net/10220/46228 |
