Paper Abstract

The direct detection of extrasolar planets .by imaging will require reductions in scattered and diffracted light by factors in excess of 103 within one arcsecond of a bright source. While diffraction can be reduced by a number of approaches, small angle scatter can only be reduced by controlling mid-spatial frequency figure errors. We review the surface requirements and consider their meaning when compared to the data base of existing mirrors. We describe experiments that were successful in reducing mid-spatial frequency figure so that the scatter level was 500 times less than diffraction for a 25 cm spherical mirror.
