coronagraph , także: coronograph

"Nobody has ever built a coronagraph like this before, from the ground up."

In fact, it can even be done on Earth on mountaintops, making use of a coronagraph.

Stray light is a major issue in the design of a coronagraph, used for observing the Sun's corona.

The satellite will carry as its payload an advanced solar coronagraph.

In 2001, an optical coronagraph was used to example the star, but no companion was found.

The coronagraph has recently been adapted to the challenging task of finding planets around nearby stars.

Japanese astronomers using a coronagraph saw the comet break into three pieces 30 minutes before perihelion.

Its main instrument will be a coronagraph for studying the dynamics of the Solar corona.

They are usually observed with a white-light coronagraph.

The values are only lower limits, because coronagraph measurements provide only two-dimensional data analysis.

A coronagraph requires very high-quality optics assembled in a dust-free atmosphere.

In the 1960s the observatory was enhanced with a coronagraph; a device that enabled research to be carried out on the atmosphere of the sun.

This technique is similar to a coronagraph but uses multiple sources rather than a physical obstacle to block out the unwanted signals.

It is a type of coronagraph.

Ring Around the Sun Q. How does a coronagraph work?

They then began the repair operation, replacing the satellite's attitude control mechanism and the main electronics system of the coronagraph instrument.

An updated version of this design is called the Starshade, which uses a sunflower-shaped coronagraph disc.

A band-limited coronagraph uses a special kind of mask called a band-limited mask.

Improved his coronagraph.

An optical vortex coronagraph uses a phase-mask in which the phase-shift varies azimuthally around the center.

This is because the complete absence of atmospheric scattering eliminates the largest source of glare present in a terrestrial coronagraph.

Dr. Bernard Lyot developed the first coronagraph to study the Sun's corona.

Throughout the 1930s, he labored to perfect the coronagraph, which he invented to observe the corona without having to wait for a solar eclipse.

The Starshade acts as a very large coronagraph: it blocks light of a distant star, making it easier to observe associated planets.

The coronagraph, using interference, masks out the light along the center axis of the telescope, but allows the light from off axis objects through.
