Frequency Domain Optical Coherence Tomography (FDOCT) Joon S Kim IMSURE Summer Research Fellow At Beckman Laser Institute University of California at Irvine Irvine, CA 92612 Email: [email protected] Faculty mentor: Prof. Zhongping Chen Lab mentor: Jun Zhang Abstract-An optical coherence tomography (OCT) is a noninvasive imaging technology in which an amplitude and a phase of electromagnetic wave undergone backscattering are used to extract properties and microstructure of a material medium such as biological tissues by providing a cross-sectional view of the sample being scanned. In an OCT experiment, the precise control of laser source plays crucial role in obtaining accurate data. Reflecting this point, the use of high-tech hardware and control software ranging from voltage controlled laser generator to the high speed digitizer which maintains a consistent and precise triggering of rapidly evolving information-bearing signal are pervasive and thus, integral part of OCT experiment.
