interferogram|ɪntəˈfɪərəʊgræm|
[f. interfere v. + -o + -gram.]
A pattern formed by the interference of radiation, esp. one represented in a photograph or diagram.
1921Trans. Optical Soc. XXII. 185 Fig. 12 represents an interferogram as seen on one of the lens interferometers described, the thick lines representing dark bands. 1949Jrnl. R. Aeronaut. Soc. LIII. 637/2 The interferograms give the density variation across the mixing zone. 1959Physics of Fluids II. 165 (caption to photograph) Monochromatic interferograms taken simultaneously at λ = 4122 A and 5463 A of an ionizing shock wave in argon... The fringes move upward with increasing refractivity. 1965E. B. Brown Mod. Optics viii. 440 The intensity plots..are referred to as interferograms, and the interferometers used in this fashion are often called interferometer modulators. 1966D. G. Brandon Mod. Techniques Metallogr. 27 For first-order interference at λ = 5,500 Å with a high refractive index oil between the plates..the cone angle a that can be tolerated is..about 25°, corresponding to a 0·65 NA objective, and critical illumination can be used to form the interferogram. |
