The New Worlds Observer Concept The New Worlds Observer consists of two
spacecraft as shown in Figure 1, the first is an Occulter, and casts a shadow into
which the Telescope craft is flown. The idea of an occulter is very simple. When
we ...
Claude Aime, Farrokh Vakili, 2006
A three-disk external occulter shades the objective lens from direct solar radiation
and creates a deep shadow at the objective lens aperture (A1). A heat rejection
mirror reflects incident solar radiation back through the entrance aperture.

Furthermore, the intensity of the starlight in the shadow of the occulter is not zero;
it must be computed with Fresnel's diffraction theory (e.g., Born and Wolf 1997).4
Application of Babinet's Principle gives the approximation (Schultz et al. 1999) I ...

The apodized occulter design given in the previous section provides the starlight
suppression necessary to image an Earth-like planet. But, sensitivity analyses
show that it is not possible to build such an occulter with adequate precision.

3.3.1 The Chopper Technique In this techniqne the source signal is suppressed
by blocking the field of view with a so-called occulter. The occulter is a block of
heavy metal (often Pb or Wl which covers the field of view for a certain time (often

Measuring the Universe: A Multiwavelength Perspective
To avoid light diffracted by the occulter entering the telescope, the mask must be
significantly larger than the telescope aperture. To allow imaging at the telescope
diffraction limit, it must be far enough away that it is unresolved. These two ...

The leader spacecraft is assumed to be perfectly controlled. Therefore, the
responsibility of maintaining the required accuracy falls completely on the
occulter. The occulter must maintain its 50,000 km distance from the leader but is
