“…With the high spectral resolution and compactness, AWG spectrometers provide an excellent choice for SD-OCT. Recently, AWGs were used for ultrahigh-speed OCT imaging at 1:5 μm in SD-OCT through parallel signal acquisition using 256 balanced photoreceivers [9]. However, this system has the disadvantage that it uses optical amplifiers, is extremely costly, and has a high complexity.…”

ID 141269); published March 31, 2011We designed and fabricated an arrayed-waveguide grating (AWG) in silicon oxynitride as a spectrometer for spectral domain optical coherence tomography (SD-OCT). The AWG has a footprint of only 3:0 cm × 2:5 cm, operates at a center wavelength of 1300 nm, and has 78 nm free spectral range. OCT measurements are performed that demonstrate imaging up to a maximum depth of 1 mm with an axial resolution of 19 μm, both in agreement with the AWG design parameters. Using the AWG spectrometer combined with a fiber-based SD-OCT system, we demonstrate crosssectional OCT imaging of a multilayered scattering phantom.

“…In spectral domain OCT, the speed limitation arises from the line camera. A discrete spectrometer consisting of hundreds of discrete photodiodes was constructed to enable SD-OCT imaging at several MHz line rate [151]. Four line cameras have been used with sequential readout in order to achieve line rates of one MHz in SD-OCT [152].…”

Abstract:Imaging speed is one of the most important parameters that define the performance of optical coherence tomography (OCT) systems. During the last two decades, OCT speed has increased by over three orders of magnitude. New developments in wavelength-swept lasers have repeatedly been crucial for this development. In this review, we discuss the historical evolution and current state of the art of high-speed OCT systems, with focus on wavelength swept light sources and swept source OCT systems. 3067-3086 (2012). 7.

“…One calibration method is based on a specially designed spectrometer that linearly samples the wavenumber. [7][8][9] This method reduces post-processing needs but complicates system design. The other direct calibration methods proposed include a characteristic wavelength method 10 and a spectral interferogram mapping method, 11,12 which are based on directly measuring part of the wavelength distribution on the charge-coupled device (CCD) by standard equipment and then performing polynomial fitting to obtain the wavelength alignment on the whole CCD pixels.…”

Self-spectral calibration for spectral domain optical coherence tomography

et al. 2013

Abstract. A different real-time self-wavelength calibration method for spectral domain optical coherence tomography is presented in which interference spectra measured from two arbitrary points on the tissue surface are used for calibration. The method takes advantages of two favorable conditions of optical coherence tomography (OCT) signal. First, the signal back-scattered from the tissue surface is generally much stronger than that from positions in the tissue interior, so the spectral component of the surface interference could be extracted from the measured spectrum. Second, the tissue surface is not a plane and a phase difference exists between the light reflected from two different points on the surface. Compared with the zero-crossing automatic method, the introduced method has the advantage of removing the error due to dispersion mismatch or the common phase error. The method is tested experimentally to demonstrate the improved signal-to-noise ratio, higher axial resolution, and slower sensitivity degradation with depth when compared to the use of the zero-crossing method and applied to two-dimensional cross-sectional images of human finger skin.
