In this work, we use Spectroscopic Optical Coherence Tomography and Morlet wavelet transformation to deduce hemoglobin oxygen saturation in blood sample. The technique makes use of the different absorption properties of hemoglobin and oxyhemoglobin around 800 nm. In order to test the technique, we combined three superluminescent light emitting diodes together in a Fourier Domain Common Path OCT set-up...
A single-arm interferometer-based optical coherence tomography (OCT) system known as common-path OCT (CP-OCT) is rapidly progressing towards practical application. Due in part to the simplicity and robustness of its design, Fourier domain CP-OCT (FD-CP-OCT) offers advantages in many endoscopic sensing and imaging applications. FD-CP-OCT uses simple, interchangeable fiber optic probes that are easily...
We have demonstrated in vivo three-dimensional imaging and estimated localized and quantitative hemoglobin oxygen saturation (SO2) of blood vessel by using a simple, easy to operate common-path Fourier-domain optical coherence tomography (OCT) system. The common-path OCT system can be easily integrated with various surgical tools and we demonstrated its usefulness by imaging outer and inner intraocular...
We investigated a Fourier-Domain Common-Path OCT system operating at 840 nm center wavelength. The axial resolution of the system is 8.8 mum and the imaging depth is about 3.5 mm.
