Full sphere annular large visual field moon edge optical imaging object lens

Abstract

A full sphere annular large visual field moon edge optical imaging object lens belongs to the technical field of optical design and solves the defects of high manufacture and detection cost of parts and the whole machine of an optical system in the prior art, and the uncertain work stability in the space environment. A first planar mirror combination, a second planar mirror combination, an imaging lens combination, a diaphragm, a piece of detector protection glass, and a detector are coaxially arranged according to a light incident sequence. The second planar mirror combination is arranged in front of the first planar mirror combination and arranged in parallel. The first planar mirror combination includes eight planar mirrors which are circumferentially uniformly distributed around a Z axis. The second planar mirror combination includes eight planar mirrors which are circumferentially uniformly distributed around the Z axis. The planar mirrors in the two planar mirror combinations are corresponding to each other. The optical system is insensitive to a circumlunar satellite orbital altitude. The full sphere annular large visual field moon edge optical imaging object lens has high resolution imaging, high imaging quality, and high pointing accuracy, can suit the high precision attitude location of an airship in a moon reflection spectrum region, and reduces the circumlunar flight satellite attitude location time.

Description

technical field [0001] The invention relates to a spherical annular large field of view lunar edge optical imaging objective lens, which belongs to the technical field of optical design. Background technique [0002] Satellites flying around the moon need to determine their own pitch and roll attitude in real time. The traditional attitude determination using the combination of star sensor and gyroscope requires the computer on the ground and the satellite to provide accurate orbit information. The accuracy of satellite attitude determination is very dependent on the accuracy of orbit determination, and the single attitude determination takes a long time. At the same time, when the star sensor on the near-orbit satellite around the moon images the moon, the optical system needs a field of view of 100° to 150° to cover the entire moon. For a single transmission imaging lens, small optical aberrations and high The pointing accuracy is relatively difficult in design and post-p...
