Precision is sig-nificantly greater than with dilatometry, but be-cause the technique relies on the optical reflectance of the specimen surface, interferom-etry is not used much above 700 °C (1290 °F). ASTM Test Method E 289 (Ref 3) provides a standard method for linear thermal expansion of

web.physics.ucsb.eduConsider figure 2, which shows the set-up for a diffraction grating experiment. If a monochromatic light source shines on the grating, images of the light will appear at a number of angles—θ 1, θ 2, θ 3 and so on. The value of θ m is given by the grating equation shown above, so that θ m = arcsin mλ d
