摘要
A multi-order diffractive Fresnel lens (MOD-DFL) that is suitable for use in a space telescope for studying transiting earth-like planets of distant stars is provided. The MOD-DFL may comprise a MOD-DFL array comprising a plurality of MOD-DFL segments that are secured to a mounting surface of a deployment device, such as a balloon, for example, in a preselected arrangement to form the MOD-DFL. An array telescope may be formed of an array of deployment devices, such as an array of balloons, for example, each having a MOD-DFL secured to a mounting surface of the respective deployment device, an optics system disposed inside of the respective deployment device, and a camera disposed inside of the respective deployment device. Each MOD-DFL comprises a plurality of MOD-DFL segments arranged in a preselected arrangement to form the respective MOD-DFL.
