Abstract

We report on work to construct a dispersion control system using a spatial light modulator (SLM) in conjunction with optical coherence tomography. To test feasibility of the dispersion control system, we simulate the group delay by water, analyze phase of coherence function, and compute the dispersion compensating function for the SLM. In addition, a unique interferometer configuration utilizing the SLM is described. We verify that dispersion information in optical coherence imaging can be measured by phase analysis of coherence function in optical frequency domain and modified for a variety of applications using the control system.
