Spatial Frequency Domain Imaging (SFDI)

Introduction

Measurement of minute components and various aspects, especially around nature, requires specialized techniques and science to classify them. Fiber on soft tissues – for instance on leaves – can effectively be viewed and counted using high amounts of transmitted light. Spatial Frequency Domain Imaging is among the methods and techniques that help to separate the impact of scattering and absorption to ensure accuracy of the quantification process. Ultimately, monitoring of the tissues for early-stage burns helps to give appropriate treatment and management of wounds. The purpose of this paper is to describe Spatial Frequency Domain technology in order to simplify the process and make it comprehensive. The spatial Frequency Domain works with Polarized Light Imaging (PLI) to easily present fiber for easy view on how they are repeated per unit of distance.

How Spatial Frequency Domain technology works

The innovation works by first shinning various patterns of light onto a tissue. A video recording of the process to capture the remitted light and efficient processing of the video clip is necessary. The burns may be visually similar, but they differ in their progress, consequently needing different clinical treatments. The clinical observation can distinguish between minor and full-thickness burns, making diagnosis quick and efficient.

The innovation has made the calculation and determination of soft tissue fiber orientation possible and effective. It utilizes polarized light imaging technology to take advantage of the scattering property of fibers in diagnosing the various orientations. The result is the highlighting of photons that are scattered from the superficial layer. Today, it is, therefore, possible to determine and quantify fiber orientation with optical sectioning. At a specified spatial frequency, the imaging process and depth is limited, leading to higher accuracy in the ultimate quantification.
