Introduction to Thermal Cameras

Introduction to Thermal Cameras
The roots of thermography go all the way back to the year 1800 when a German astronomer by the name of Sir William Herschel performed various experiments with light. Herschel had an idea to hold a prism up and let the sunlight filter through. As you know, a prism will emit various colors of light depending on where it hits in the prism. Sir William Herschel had an idea to… Continue Reading »

Cracking Towers

Cracking Tower
Refineries use large “cracking towers” as a part of their operations. These towers can be approximately 100 feet tall and are filled with a catalyst that assists the conversion of oil into lighter fuels. Periodically, the catalyst must be removed, the tower cleaned out, and new catalyst added. In order to remove the old catalyst, workers must enter and remain inside the tower wearing full protective gear. As the old catalyst is being… Continue Reading »

What is OTDR?

An OTDR is an extremely valuable tool when you are trying to characterize optical fibers. OTDR (optical time domain reflectometers) units are used to locate any events in your fiber cable and the amount of attenuation of the fiber. An OTDR uses the effects of Rayleigh Scattering and Fresnel Reflections to measure characteristics in your fiber. The OTDR will send a light pulse down your fiber and by measuring the time it takes for… Continue Reading »
