Embodiment Construction

[0026] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0027] like figure 1 As shown, the present invention provides a telephoto imaging device with high angular resolution including a telescope 1, a collimating mirror 2, a mirror 3, an oblique wavefront corrector 4, a high-order wavefront corrector 5, a beam reduction system 6, a first Spectroscope 7, wavefront modulator 8, imaging module 9, first reflector 10, second spectroscope 11, Shack-Hartmann wavefront sensor 12, second reflector 13, fine tracking wavefront sensor 14 and Wavefront controller 15;

[0028] After the light passing through the telescope 1 is collimated by the collimating mirror 2, it is sequentially reflected by the mirror 3 to the oblique wavefront corrector 4 and the high-order wavefront corrector 5 for correction to obtain the corrected light; the corrected light enters the beam reduction system 6 to reduce the beam to obtain Reduce...

Abstract

The invention discloses a telescopic imaging device with high angular resolution, which comprises a telescope, a collimating mirror, a reflector, an inclined wavefront corrector, a high-order wavefront corrector, a beam shrinking system, a first spectroscope, a wavefront modulator, an imaging module, a first reflector, a second spectroscope, a Shack-Hartmann wavefront sensor, a second reflector, afine tracking wavefront sensor and a wavefront controller. The adaptive optical system of the device can correct the influence of atmospheric turbulence on telescopic imaging, and the wavefront modulator can diffract and compress the point spread function of the telescopic imaging device, so that higher resolution is obtained, and the device has an important technical application prospect in thefield of telescopic imaging research.

Description

technical field [0001] The invention belongs to the technical field of telescopic imaging, and in particular relates to a telescopic imaging device with high angular resolution. Background technique [0002] Telescopes are an important tool for humans to conduct remote sensing observations of space debris, celestial bodies or the earth. Due to the diffraction behavior of light waves, the angular resolution of an ideal telescopic imaging device is limited by the operating wavelength and the aperture of the telescope. Generally speaking, the working wavelength of the telescopic imaging device is relatively fixed, and obtaining higher angular resolution means increasing the aperture of the telescope. However, the technical difficulty and development cost brought about by the preparation of large-aperture telescopes will increase sharply. Therefore, how to break through the above-mentioned theoretical limitation of the angular resolution of the telephoto imaging device and ach...
