1 Resonance Methods for Increasing Sensitivity of Interferometry …
Fig. 1.5 Scheme of recording a hologram of diffusive screen for determining spatial coherence
function: 1—the laser under investigation; 2—the rectangular diaphragm, 3, 5, 10—the deflecting
mirrors; 4, 11, 12—the lenses, which design the laser end image and rectangular diaphragm onto
the hologram and diffusive screen; 6, 9—the mobile mirrors system used for flattering of the path
difference of object and reference beams; 7—the lens, which designs laser end intensity distribution
onto the film (8); 13—the diffusive screen; 14—the hologram. Laser LG–55 is used for the scheme
adjusting. Combination of dye laser beams and LG-55 has been achieved using the plates 15 and
output mirror 10 (see Fig. 1.11). Reprinted from [54] with permission
Fig. 1.6 Scheme of wave front reconstruction and intensity registration: a when determining SCF
by a holographic method; b when determining SCF by an integral method. Reprinted from [54]
