Paper Abstract

Optical coherence tomography (OCT) is a well known microscopy technique used to observe micrometer structures in biological samples. Here we propose new experimental OCT setups using one Michelson interferometer and a CCD camera. Unlike the standard time domain OCT setup, our approach allows for high resolution imaging of a sample without any mechanical motion of the mirrors or the sample. The OCT signal is directly obtained at the CCD camera and does not require Fourier transformations or any mathematical operation as in Fourier domain OCT. The speed of data acquisition is not limited by any mechanical displacement or calculations but only by the camera throughput.
