History
The first optical dilatometer was invented by Abbe and Fizeau in the second half of 19th century. This design has a reflected beam of monochromatic light and the measurement of the displacement is carried out by counting the interference fringes between the forward going beam and the reflected beam. After the Abbe invention, many improvements were achieved on the original design and there are now many models available on the market, which use modern optics and designs.
Over the last five decades, interest has grown in the use of thermomechanical technologies for characterising materials in different fields of science and engineering. In particular, the use of optical methods has been playing a role in the field of ceramics and have been used to measure the coefficient of thermal expansion of bodies and glazes in order to ensure an optimal match of their thermomechanical behaviour.

Famous quotes containing the word history:
“The history of literature—take the net result of Tiraboshi, Warton, or Schlegel,—is a sum of a very few ideas, and of very few original tales,—all the rest being variation of these.”
—Ralph Waldo Emerson (1803–1882)
“It takes a great deal of history to produce a little literature.”
—Henry James (1843–1916)
“Perhaps universal history is the history of the diverse intonation of some metaphors.”
