The first planetarium was a mechanical miniature of the solar system, which was completed by hand according to the clock manufacturing technology. It was not until the emergence of mechanical optical projection astrologer that the word astrologer became familiar to people.
Astrologer is a combination of high-quality optical and mechanical projection system and precise digital control technology, specially designed for large spherical screens and multimedia cinemas. Because the brightness of all the projections is very high, it can be used even if the reflectivity of the projection surface is very low, and the traditional white projection spherical screen is not needed.
Gray ball screen will greatly improve the clarity and color saturation of slide and video projection. The system follows the latest star instrument concept, that is, the star sky projector and the solar system celestial projector are mechanically separated.
Structure:
Stellar instrument is a spherical projector, which demonstrates all starry phenomena and teaching projections with high image quality. It can rotate around three combined axes and simulate all astronomical movements. Solar system projectors are placed separately, and also have three independent motion axes, which are used for object positioning and image rotation respectively. The motion and brightness control of star instruments and solar system projectors follow astronomical algorithms.
Each individual projector can also independently use astronomical data for movement, function switching, brightness and moon ratio. Planetarium can integrate or separate a single projector from the whole astronomical system as needed. The third component, independent of the star instrument and the solar system projector, is a control system, and the control equipment is convenient.
