Transmission Mode Full-Field Swept-Source Optical Coherence Tomography for Simultaneous Amplitude and Quantitative Phase Imaging of Transparent Objects

A transmission mode full-field swept-source optical coherence tomographic system is demonstrated for simultaneous amplitude and quantitative phase imaging of transparent objects. The experimental setup consists of a swept-source system, fiber-optic Mach-Zehnder interferometer, and an area detector. By means of sweeping the wavelength of light source, multiple interefrograms were recorded and both amplitude as well as phase images of the multilayer object and onion skin were reconstructed. The main advantages of the present system are: light passes through the sample only once; high throughput; wide field; compact; and completely nonmechanical scanning.
