Three Dimensional Millimeter- and Terahertz-Wave Imaging Based on Optical Coherence Tomography
نویسندگان
چکیده
Three dimensional (3D) terahertz (THz) imaging or THz tomography has recently proven to be useful for non-destructive testing of industrial materials and structures. In place of previous imaging techniques such as THz pulse or continuous wave (CW) radar, we propose a THz optical coherence tomography (OCT) using frequency-swept THz sources, and demonstrate 3D imaging. In addition, we further apply this technique to the millimeter-wave region in order to extend applicable targets. key words: imaging, tomography, optical coherence tomography, terahertz, millimeter wave

Development of an Advanced Optical Coherence Tomography System for Radiation Dosimetry
Introduction: According to the literature, optical coherence tomography (OCT) can be used measure radiation absorbed dose. This study was carried out to design a computed tomography system for the calculation of absorbed dose and optimization of dose delivery in radiotherapy using gel dosimeters. Material and Methods: An advanced charge-coupled device based OCT system was developed in laborator...
متن کاملHigh-resolution three-dimensional imaging of biofilm development using optical coherence tomography.
We describe the use of optical coherence tomography (OCT) for high-resolution, real-time imaging of three-dimensional structure and development of a Pseudomonas aeruginosa biofilm in a standard capillary flow-cell model. As the penetration depth of OCT can reach several millimeters in scattering samples, we are able to observe complete biofilm development on all surfaces of a 1 mm x 1 mm flow-c...
متن کاملTerahertz Imaging Progress at Capital Normal University
The progress on terahertz imaging at Capital Normal University in Beijing is presented. Our works on Terahertz Imaging include the active and passive imaging. For the active terahertz imaging, the pulse and continue wave terahertz imaging are studied, respectively. The active terahertz pulse imaging is based on the terahertz time-domain spectroscopy (THz-TDS). A practical focus-plane imaging sy...
متن کاملFull wave model of image formation in optical coherence tomography applicable to general samples.
We demonstrate a highly realistic model of optical coherence tomography, based on an existing model of coherent optical microscopes, which employs a full wave description of light. A defining feature of the model is the decoupling of the key functions of an optical coherence tomography system: sample illumination, light-sample interaction and the collection of light scattered by the sample. We ...
متن کاملApplication of the diffracted gaussian beam analysis method in terahertz
The use of millimeter and sub-millimeter wave antenna systems for the studies of space is of great significance to astronomy. This paper presents the application of Diffracted Gaussian Beam Analysis method (DGBA) in Terahertz. And a three dimensional visual software based on DGBA is used for the simulation of a single-channel quasi-optical system at 325GHz. The simulation results and comparison...
