1. phase resolved system based on swept source optical coherence tomography (SSOCT) called as phase-sensitive SSOCT to detect and quantify gas microbubbles in aqueous and tissue simulated media is developed. The structural images of gas microbubbles are obtained using conventional SSOCT, while common path SSOCT was used to perform the phase-sensitive measurements. The system shows an axial resolution of 10 µm, a phase sensitivity of 0.03 rad, an imaging depth of up to 6 mm in air, and a scanning speed of 20 kHz for a single A-line. The structural images of the bubbles show an accuracy of 10 µm, whereas ... (Read Full Article)
