Background technology
Astronomical telescope is the main tool of modern astronomy exploration of the universe.The astronomical telescope device generally divides equatorial astronomical telescope and altitude azimuth form astronomical telescope.The equatorial astronomical telescope has two mutually perpendicular axles to be.An axle is parallel with earth's axis, and promptly it equals local geographic latitude with the angle of cut of ground level, and this axle is called as " right ascension axle " or " pole axis ".Pole axis is a tracking axis, and telescope is when following the tracks of apparent diurnal motion of heavenly body, with the pole axis rotation of unrolling of the 24 hours/rotating speed that changes.Another root axle is followed the tracks of the fixed star celestial body " declination axis " for observation, the pole axis rotation, and declination axis only rotates when pointing to the observed object star.
What middle-and-high-ranking astronomical telescope adopted nearly all is the equatorial astronomical telescope, only requires that pole axis gets final product with speed identical with fixed star and direction rotation because the equatorial astronomical telescope is followed the tracks of the sidereal time, and telescope control is relatively accurate, and it is also convenient to install.The tram of equatorial astronomical telescope pole axis should be that pole axis points to the celestial sphere limit, and declination axis is perpendicular to pole axis, and in the celestial equator face, has only in this case, and telescope could rotate consistent with the Sunday in the vault of heaven around the rotation of pole axis.
The precision that the pole axis of equatorial astronomical telescope is aimed at the celestial sphere arctic directly has influence on tracking accuracy; And the celestial sphere arctic does not have proper reference star, though Polaris often is considered to celestial north pole, has the deviation that surpasses 0.5 degree with celestial north pole; This is to the tracking of high request; Especially long-time the shooting is worthless, because the celestial body that will follow the tracks of is through running out of outside the following range, so need very accurately declination axis (pole axis) to be pointed to celestial north pole after a while.
The equatorial astronomical telescope of prior art generally carries out after observation finishes the correction of pole axis, and can impact (observation especially for a long time) to ongoing observation.The correction of the pole axis that when using the equatorial astronomical telescope, carries out is also arranged in the prior art; Such as: through the auxiliary method of adjusting the right ascension axle sensing of equatorial astronomical telescope of pole axis mirror; Yet this method or too loaded down with trivial details and enough knowledge of needs and data; Precision is not enough, has a strong impact on observation quality: equatorial astronomical telescope pointing accuracy and tracking accuracy are important indicators of telescope itself, and they receive the influence of pole axis positional accuracy; The pole axis position is extremely important accurately, and how in real time, accurately, simply the pole axis correction of therefore carrying out the equatorial astronomical telescope becomes one of direction of current research.
