occulter उदाहरण वाक्य

The LASCO C-3 coronagraph uses both an external occulter ( which casts shadow on the instrument ) and an internal occulter ( which blocks stray light that is Fresnel-diffracted around the external occulter ) to reduce this " leakage ", and a complicated system of baffles to eliminate stray light scattering off the internal surfaces of the instrument itself.
