Abstract
We introduce the concept of tuning in the low-coherence trans-illumination interferometer to enhance its overall applicability (i.e., to enable selective diagnosis from different tissue regions). Modulation artifacts of the tuned interferometer are restricted to the reference arm. Displacements in this system, for pass-through photon-based modality, must be inverted. Tuning of specific radiation depends on modulation parameters and coherence-time gate. We propose to use Recurrence Plots and Recurrence Quantification Analysis (RQA) as a robust platform to identify different tuning states in the trans-illumination experiment. To the best of our knowledge, this is the first time that recurrence analyses are employed in trans-illumination studies. We suggest the quantitative metric of Determinism as a reference to assess the degree of tuning of the instrument. Theoretical results confirm that RQA may be useful for discriminating between different tuning states, including photon isolation for pass-through photon-based biomedical trans-illumination.
