High resolution imaging self-adaptive optical telescope suitable for working at daytime

Abstract

The high-resolution adaptive imaging optical telescope comprises: a telescope system, a precise track system with EMCCD (reading noise < 1e-) as the core detective member, an adaptive optical system, and an imaging system, wherein the precise track and detection system is arranged in Kuder room to keep all of the track system and track loop and high-order error correction loop on one OA; the Hartmann sensor works on near-IR range to reduce background effect, and the near-IR detector in imaging system can overcome effect from strong back light and air turbulence to improve imaging resolution.

Description

technical field [0001] The invention relates to a telescope, in particular to a high-resolution imaging adaptive optics telescope suitable for daytime work. Background technique [0002] Adaptive optics is a system that detects and corrects random optical wavefront aberrations in real time. Conventional adaptive optics telescopes work in the visible light range. On page 943 of SPIE published in 2004, the working band of the fine tracking circuit of the Yunnan Astronomical Observatory 1.2m Adaptive Optics Telescope is 0.4um-0.43um, and the working band of the high-precision tracking circuit and high-order error correction circuit is 0.43um-0.7 um, the working band of the imaging system is 0.7um-1.0um. Due to the high intensity of the sky background in the visible light band, this adaptive optics telescope does not have the ability to work during the day; at the same time, the precision tracking system is located at the bottom of the telescope barrel, and the high-order erro...
