Raman spectroscopy provides important information about
materials. When laser light hit a sample, a small percentage of the
scattered light may be shifted in frequency. The frequency shift of the
Raman scattered light is directly related to the properties of the
sample material. A Raman spectrum provides a “fingerprint” that is
unique to the material. Raman spectroscopy is employed in many
applications including mineralogy, pharmacology, corrosion studies,
analysis of semiconductors and catalysts, in situ measurements on
biological systems, and even single molecule detection.
Many medical institutions have tried various lasers for treatment of chronic rhinitis .
There are many advantages of laser performance.
Energy Dispersive X-ray Fluorescence or EDXRF is known to
scientist at least 50 years. It became very favorable tool to measure
chemical compositions about 30 years ago. This is due to ability to
produce by many companies a portable X-ray source and small Si-pin
It is not a myth anymore. Many people start using red and infra-red
lights to fight different health problems. In this article we will try
to describe in general terms what does science and medical world know
and uses for healing in terms of light.
1. A LASER source to excite the target (measured sample).
Infrared, or IR for short, is very dangerous because human eye can’t see
it. I remember my first experiments with 5W solid state laser.
