| Abstract: |
By combining the starlight received by two telescope apertures out of phase, on-axis starlight can theoretically be nulled out, leaving any possible planetary companions and exozodiacal light more easily detectable. However, such an approach is only possible if several very stringent conditions are met by the optical system. Herein the various optical requirements are enumerated and tabulated. In addition, initial laboratory nulling experiments carried out at JPL are described. To date, a laser diode has been successfully nulled to a part in 25,000. |
