ABSTRACT
We review image acquisition strategies and techniques studied
and developed to achieve high-speed imaging of full-field optical
coherence tomography (FF-OCT). Usually, the time domain FF-OCT
imaging has employed conventional phase-shifting interferometry
in which at least three interference images, for example with
quadrant phase shifts, were needed to extract one coherence-
gated tomogram image [1-6]. Such imaging process may be time
consuming and not suited for in vivo imaging of mobile biological
samples. Recently, many techniques to improve the FF-OCT imaging
speed have been proposed, and they suggested great potentials for
the in vivo imaging of living specimens. In this chapter, we will
review the FF-OCT imaging schemes in terms of principles and
processes. For effective reviewing, it is categorized into two main
sections: (1) high-speed 2D FF-OCT imaging and (2) high-speed
3D FF-OCT imaging. For each section, various recent efforts for
enhancing the imaging rate will be presented and analyzed in detail.
In general, interference signals in a FF-OCT system are recorded
by a 2D image sensor array such as a charge-coupled device (CCD)
camera. The light intensity delivered to each pixel at a point (x , y) on the CCD plane can be expressed as [7]
