Abstract

The signal expression measured by an OCT system is derived, which reveals the possibility of tissue dispersion compensation by introducing the required amount of dispersion in the reference arm and may be implemented by incorporating the grating- based rapid scanning optical delay (RSOD) lines in the reference arm of OCT. The more accurate expressions for the group-delay dispersion (GDD) and the second-order GDD are derived for the grating-based RSOD lines. A comparison of our results with previous ones is done, which shows that when only the GDD is of concern, the previouslyreported results are accurate. However, when it becomes necessary to take the effect of the second-order GDD into account, the more accurate formula must be used. The obtained results may be of great importance for maximizing the imaging properties of OCT in tissue imaging.
