Abstract
In a OCT interferometer it is necessary to balance dispersion within the reference arm with dispersion within the object arm. This is normally done by replicating within the reference arm the components found in the object arm. This adds to the complexity and cost of the OCT interferometer. A method is provided for determining the design of and designing a simplified OCT interferometer, in which the reference arm contains only a single piece of glass of a single glass type. This reduces the cost and complexity of the OCT interferometer, and reduces power loss and undesired reflections within the reference arm.
