My passions are teaching, inventing and developing new side illuminated (vs axial illuminated) optical fiber sensors. It has been twenty eight years since I started working in this field at NASA Langley. The goal was to create a nervous system for Smart Structures.
First, I started working in a theoretical model to understand light propagation in a side illuminated fluorescent cladding fiber. At the time, many believed that the signal in this fiber would decrease with the core/cladding refractive index difference. I discovered otherwise: an unexpected result!
Next I demonstrated that side illumination had a fluorescent signal stronger than axial illumination. Later on, I used simple lightmeters, instead of expensive spectrometers, to read the fiber signal. This replacement, opened the doors to a far more rugged, stable and powerful systems.
In 2003, I demonstrated the first side illuminated fiber sensor with a very high density of sensing points: one sensing point for every 5 mm of fiber. Unfortunately, in 2007, others started to claim precedence of this result. This contrasted with the prevailing wisdom of using axial illumination with OTDRs and other expensive detection schemes: a higher cost solution producing far worse spatial resolutions.
In 2005, I demonstrated a side illuminated fiber that uses absorption indicators instead of fluorescent ones. Further configurations came with the use of bare core fibers with no indicators.
After these discoveries, the side illuminated optical fiber sensor became far more useful. As a result I have been using several optical properties in conjunction with this illumination concept: with and without a sensitive cladding.
I am now engineering this concept and looking forward to start its full commercialization.
Specialties: Expertise in the development of optical fiber sensors for several industries including water, construction, agriculture, aerospace, environmental monitoring and others.

Developing optical fiber sensors for the water, medical, construction, agricultural, educational, environmental and other markets.
Dr. Egalon pioneered and reduced to practice the first multi point side illuminated optical fiber sensor and holds several patents on this concept: both in the US and overseas. His patents on side illumination cover the following devices:
1. A fluorescent cladding with multiple sensing points.
2. An absorption based cladding sensor.
3. A bare core fiber for optical measurements.
4. A tapered core fiber with and without an active cladding.
5. An optical fiber with a very high density of sensing points: at least one point for every 5 mm of fiber.
6. Simultaneous sensing from multiple sensing points with a single detection system and others.
With current technology, such as LED print heads with 1,000 LEDs/cm, it is possible to design a side illuminated sensor that can accommodate one sensing point for every 10 microns of fiber. This unexpected capability can be considered the precursor of the first artificial nerve. For comparison purposes, the human hand averages 2,500 nerve endings per square centimeter. Dr. Egalon's sensors have the capability of producing 1,000,000 sensing points per square centimeter: 400 times denser.
Dr. Egalon has been an SBIR grantee with the NSF and the USDA Programs and the Brazilian SBIR-like program funded by FAPESP: Foundation for Research of the State of Sao Paulo. Under these grants he demonstrated the following devices:
1. A reversible chloride ion sensor for concrete structures and water.
2. A reversible relative humidity, RH, sensor for concrete structures and air.
3. Analysers for nitrate, phosphate, calcium and magnesium.
4. A reversible turbidity sensor.
5. A low cost liquid level sensor with the potential for nanometric spatial resolution and
6. A unique optical fiber device that can make colorimeteric, fluorimetric, scattering and index of refraction measurements from multiple samples.

Physics Notes: Mechanics, Fluids and Thermodynamics
Claudio Oliveira Egalon
These notes are the result of 13 years of experience teaching Physics. In this ebook, we introduce the reader, right from the start, to the building blocks of Physics: the Basic Quantities (length, time, mass, temperature, electric charge, quantity of a substance and luminous intensity); the Basic Definitions (position and force) and the Laws of Physics. These are then used to define the other quantities and definitions that are a combination of the Basic ones. By following this procedure, we demonstrate that the whole framework of Physics depends on very few ideas which are then capable of generating the knowledge that use to explain,and predict, many phenomena in our Universe.

Side Illuminated Optical Fiber: Lab Manual
Claudio Oliveira Egalon
A side illuminated optical fiber sensor was first demonstrated in 1989 by AT&T Bell Labs’ scientists. Their device was sensitive to oxygen and had a fluorescent cladding: for the next 16 years, this remained the only configuration known to the community. Unfortunately, these pioneers abandoned their own creation and the task of championing this technique befell upon this author. During this journey I discovered many other configurations that were far more cost effective and practical. If at the beginning these side illuminated fibers were fluorescent-based devices attached to expensive spectrometers and excited by massive light sources, today we have compact and inexpensive devices that can be used to make absorption, scattering and index of refraction measurements. One of the configurations developed is an optical fiber colorimeter that can make measurements from multiple samples with a single detection system. Due to its simplicity, low cost and high SNR, these configurations could had been developed and commercially deployed in the early/mid 1990’s. However, it is puzzling it did not get much attention: especially in view of the fact that axial illumination is still plagued by expensive instrumentation, low spatial resolution and low SNR Until 2001, side illumination was exploited only in the US but soon interest grew in Europe, Brazil, India, Canada, South Korea, China, Australia and Hong Kong. Between 1989 and 2003, only 10 technical documents were published: in the following 11 years 47 new documents were added to this list. So, what was initially neglected is finally gaining attention within the community. In this lab manual, we present a series of experiments that can be performed with this technology. Whether you are professional instructor or researcher, a high school, undergraduate or graduate student, you will appreciate many of the advantages and benefits of this technique that remained neglected for so many years.

Experiments in Physics: Mechanics and Fluids
Claudio Oliveira Egalon
This lab manual describes a series of experiments for undergraduate students. Throughout its pages we present a detailed step by step procedure to perform your experiments. Unlike many Physics Lab Manuals, we use statistical principles to determine the confidence level of your regression curve with respect to your data. Whereas many statistical tables publish only the values of the correlation coefficient, R, for 90%, 95% and 99% confidence levels, we published an extended version of this table in Appendix I that will allow you to determine your confidence level up to 99.99999%.
