All Dome Laser Image Projector

from Wikipedia, the free encyclopedia

All Dome Laser Image Projector , shortly ADLIP (German: laser all-dome projection system ) is a projection system in planetariums , which may represent the entire dome moving images. The image is built up by several moving laser beams, each of which illuminates clearly defined areas of the inside of the dome. The number of areas is determined by the size of the dome.

Such a system basically consists of laser beam sources , the optics for image display and control electronics. RGB lasers are used as lasers. The optics for image generation essentially consist of scanner mirrors that deflect the laser beam and optics that project the image into the dome. The electronics are responsible for importing the data, controlling the optical systems and the lasers, and monitoring the entire system.

The system was developed by Jenoptik (RGB laser) and Zeiss (optics). Compared to conventional systems, the main advantages are that the dome of the planetarium does not require any structures such as projectors, etc. to generate images , as the light is guided via glass fibers. In addition, the system is characterized by an extremely high image resolution, high image sharpness and, due to the laser radiation as the light source, a very large color space. The main disadvantage is that all programs have to be specially created for this system and older productions cannot be used for the time being.

This system was installed in the Beijing Planetarium as well as in the Jena Planetarium , but has since been replaced by newer systems.
