In this article, a method for tracking distance between a medical scope and a subject is introduced. The method considers optical coherence of light scattering due to the topography of the subject and post-processing techniques to decrease high reflection interference. The application of distance tracking is extremely important in biomedical imaging because of the effect on variance and resolution due to a non-stationary scope. Near Infrared light is considered in this article because of the application to Near-infrared (NIR) fluorescent imaging in an emerging biomedical imaging field. Many scopes currently use time-of-flight sensors to track distance, but the increasing importance on smaller technology has created a need for new implementations of current technologies. This research aims to provide evidence of an efficient system for tracking distance using post-processing to eliminate the need for additional sensing.
