What is the basic principle of fiber sensor?
A fiber optic sensor in general consists of a light source. The light source is coupled to an optical fiber. A light source which receives signal-carrying light beam on it emerges from the fiber. The signal from detector is processed electrically for getting information.
How many Light sources are available for optical fiber?
There are 142 light sources. The types of light forms are Natural which are Celestial and atmospheric light, terrestrial, and nuclear or high energy related. Other categories are direct chemical, electric powered, electron stimulated, incandescent lamps, electroluminescent lamps, gas discharged lamps, high intensity discharge, laser, combustion, nuclear, and others.
What light sources emits only a continuous spectrum a. hydrogen gas b. mercury lamp c. sodium lamp d. incandescent lamp e. laser?
d. incandescent lamp
Who was the inventor Mr Swan?
Mr. Swan or Mr. Joseph Wilson Swan is a British physicist and chemist who became famous in inventing the incandescent light bulb. He publicly demonstrated the incandescent lamp in the year 1878.
Why is optical fiber is small?
The light will be considered energy and that energy bounces side to side through the fiber. There is a constant loss. So the smaller the fiber the less loss you would have.
