Space Synthetic Aperture System

Abstract

The present invention proposes a spatial synthetic aperture system, comprising: a control device, a light splitting device arranged at the focal plane of the main mirror to be synthesized, a coupling assembly, a mode division multiplexing device, a dispersion device, and a signal receiving device; The sub-mirror is located on the control device, the beam reflected by the sub-mirror enters the beam splitting device, and the beam splitting device splits the received beam. A dispersion device, which subdivides the spectrum of the received light beam and then transmits it to the signal receiving device. The spatial synthetic aperture system provided by the present invention can synthesize optical sub-mirrors with arbitrary apertures, and can adjust the curvature of the synthesized large-aperture primary mirror arbitrarily, which not only saves the manufacturing cost of the large-aperture synthetic primary mirror, but also can flexibly improve the synthetic primary mirror. utilization rate.

Description

technical field [0001] The invention belongs to the technical field of optical synthesis, and in particular relates to a space synthetic aperture system. Background technique [0002] The increase in the diameter of the optical telescope can not only effectively improve the ability to distinguish nearby targets, but also improve the light-gathering ability of the optical telescope with the square law, which can effectively improve the imaging signal-to-noise ratio of dim and weak targets, expand the limit detection ability, and finally achieve more far-reaching detection. exploration of the universe. Therefore, large-diameter and large-field optical telescopes are the key to verifying the latest theories of cosmology and increasing the academic discourse power in time-domain astronomy and other fields in the future. Large-aperture and large-field optical telescopes have developed rapidly in the past two decades. In order to obtain higher sky survey efficiency and light-gath...

Problems solved by technology

Traditional large-aperture mirrors have a complex overall manufacturing process and high cost, and the curvature of large-aperture mirrors has been fixed after production, which cannot meet the needs of actual production or scientific research.
