Brief Introduction for Projection Dome

Projection dome is an emerging display technology that projects images onto a spherical dome screen through projection equipment (one or more projectors) to form a 360-degree panoramic picture. It is an essential component part of planetariums or dome theaters.

Brief Introduction for Optical Planetarium Projector

The planetarium projector is a popular science instrument that simulates starry sky performances, also known as a fake planetarium. Through the projection of the instrument, various celestial objects seen by people at different longitudes and latitudes on the earth are demonstrated on a hemispherical sky screen. Its basic principle is to restore and project the starry sky composed of optical star films onto a hemispherical dome screen through an optical lens to form an artificial starry sky.

Brief Introduction for Digital Planetarium Projector

Digital planetarium projector is a kind of astronomical instrument based on computer technology. It is composed of computer system, digital projector, loudspeaker and fisheye lens, which can demonstrate the motion of celestial bodies and show fulldome films in a semispherical dome.

Brief Introduction for Multi-Channel Dome Fusion Digital Astronomical Demonstration System

The multi-channel dome fusion system is an advanced projection technology system. It uses multiple projectors and professional fusion technology to project images from multiple projectors on a spherical screen, realizing precise fusion of multiple images through a digital processor and forming a seamless, panoramic image.
