Abstract

The invention relates to a spatial distribution type synthetic aperture optical detection method, which comprises the operation of utilizing a direct detection method, namely a synthetic aperture zero-eliminating interference detection method for detection. The direct detection method comprises the following steps of: a, plating a metal coating film on a reflecting mirror surface of a telescope; b, achieving pi phase delay through field vector inversion; c, performing pupil plane interference beam combination on the reflected light by using a holosymmetric beam combiner; and d, sampling an interference result. According to the invention, technical challenges of high sensitivity, high resolution, high contrast and the like in direct detection of extrasolar livable planets can be solved, and efficient use of observation resources can be realized; and carrying out of other detection methods such as a single-aperture telescope high-precision photometry method, a synthetic aperture Fizeau interference imaging method, a synthetic aperture star interferometer detection method and a synthetic aperture zero elimination Fizeau interference imaging method is given consideration.

Description

technical field [0001] The invention relates to a spatially distributed synthetic aperture optical detection method. Background technique [0002] With the continuous deepening of human exploration of outer space, the habitability of exoplanets and whether there is life has become an important research direction. The detection of exoplanets can be divided into indirect detection method and direct detection method. The indirect detection methods mainly include the Doppler radial velocity method, transit method, microgravitational lensing method, and astrometry method, among which the transit method is the most widely used method for observing exoplanets. However, none of these indirect detection methods can obtain planetary photons, let alone perform spectral analysis on the planetary atmosphere, so it is difficult to judge whether there are signs of life on the planet. The direct detection method can directly obtain photons from exoplanets. Therefore, compared with the ind...
