True-reflection OCT imaging

We present the concept of a so-called true-reflection OCT imaging algorithm. The algorithm is based on a recently developed analytical model of the optical coherence tomography technique, which is valid in both the single and multiple scattering regimes simultaneously. The model is based on the extended Huygens-Fresnel principle and takes into account the so-called shower curtain effect. With this new algorithm, it is possible to reduce the effects of scattering from conventional OCT images and create so-called true-reflection OCT images. This type of postprocessing is similar to the correction for attenuation often used in ultrasonic imaging. The principle of the algorithm is demonstrated experimentally by measurements on a solid phantom. Finally, the reduction of the dynamic range of the data when using the algorithm is an additional advantage of this post processing technique.
