Fiber Optic Trans Illuminating Imaging System (FOTI) is used for analyzing the light emission spectra from the human
body tissues and various cells. All the organs of human body tissues and cells contain various light absorbing
micromolecules such as Water, Monosaccharide’s, Oligosaccharides, Fatty acids, Amino acids, Minerals, Nucleotides, etc.
and macromolecules such as Carbohydrates, Proteins, DNA, RNA, Lipids, High energy compounds such as ATP’s and
phosphate groups. The signal comes in the form of a change in the intensity or the peak position of optical absorption,
fluorescence emission, reflection, surface plasmon resonance (SPR), surface-enhanced Raman scattering (SERS), and
electro-chemical potential/current under various conditions leading to the development of corresponding biosensors. All
the micromolecules and macromolecules have specific absorption characteristics. The basic principle of fiber optic
transilluminating imaging system is the irradiation of a sample and the analysis of the transmitted or reflected light. The
measurement is noninvasive technique and it is very useful for monitoring human body tissues at molecular level for
various clinical and medical diagnostic applications. Application areas include medical equipment manufacturers such as
production, environmental analysis, polymer identification, analyzing the protein content of grains in medicine and
biology. Biological samples are composed of proteins, carbohydrates, lipids and nucleic acids. Each of these organic
molecules has a unique chemical composition and a unique absorption spectrum. Fiber optic transilluminating imaging
system allows quantification of the sample based on their absorption spectrum.
