Summary

Description
English: The schematic of the Convergent beam electron diffraction technique. The electron beam falls into the specimen, interaction occurs and diffraction spots can be seen on the detector. α is the semi-convergent angle, Δf is the defocus distance, θ B is the Bragg angle of the specimen, a is the width of the diffraction disks and b is the distance between the 000 disk and the hkl disks.
