Several papers have been reported to check the collimation of a laser beam.[1]–[7] A
diffraction-limited beam can be obtained with ease, and hence high sensitivity is demanded …

Several schemes for checking collimation of a light beam based on the self-imaging (Talbot
effect) combined with the moire technique have been described.[1]–[4] When a grating is …

Two techniques are proposed for beam collimation with the Talbot interferometer. One is
called the mismatch method in which two gratings with slightly different periods are used. In …

We investigate the testing of collimation by Talbot interferometry with circular gratings.
Circular gratings are immune to misalignment owing to rigid body rotations in a plane …

The double grating shearing interferometry method for determination of the degree of light
collimation is described. High accuracy is obtained by performing the observation of fringes …
