The effectiveness of an optical coherence tomography (OCT) system depends largely on the light source chosen. Published data on the optical properties of tissues are used to quantify the exponential attenuation of broadband light on transport through tissue. The effective attenuation coefficient is taken to be the sum of the absorption and scattering coefficients. This is used to demonstrate the effect on the spectra of a wide range of published OCT sources and the change in system resolution induced, and hence to comment on the suitability of different sources for OCT. The tissues studied include skin dermis, liver, and gallbladder. Sources at higher wavelengths are shown to be capable of high-resolution OCT imaging at greater depths. Titanium:sapphire lasers would be most suited for high-resolution OCT over comparatively shallow depths into tissue. For lower-resolution applications of OCT, a semiconductor optical amplifier and ytterbium fiber sources have better powers and bandwidths than superluminescent diodes. The resolution of OCT systems is not reduced significantly with imaging depth.

“…The laser spectrum spans wavelengths from 1,230 to 1,580 nm. The peaks in the output spectrum correspond with regions of net fit assuming a 14 fs pulse duration [38] negative intracavity dispersion caused by the oscillations in the D2 of the DCM's. Figure 19.13c shows an interferometric autocorrelation of the laser output.…”

“…Recent efforts were focused on developing even broader bandwidth light sources in the 1,300 nm wavelength range permitting OCT micrometer-scale resolution along with up to 2 mm penetration depth. A laser spectrum covering the 1,230-1,580 nm wavelength region with an optical bandwidth of 250 nm (FWHM) was generated directly out of an all-solid-state Cr:forsterite laser [38,39]. A schematic of the laser is shown in Fig.…”

“…Recent efforts focused on developing even broader bandwidth light sources in the 1,300 nm wavelength range that would permit OCT micrometer-scale resolution along with millimeter range penetration depth. As an example, broad bandwidth light covering the 1,230-1,580 nm wavelength region with an optical bandwidth of 250 nm (FWHM) was generated directly from an all-solid state Cr:forsterite laser [67]. Figures 9.14 and 9.15 show examples of ultrahigh-resolution OCT imaging of normal and pathologic human tissues ex vivo [68][69][70].…”
