Consejo Superior de Investigaciones Científicas posted this:Scalable aperture-combined optical telescopeCSIC and the Astrohita Foundation have developed a telescope, which comprises several optical assemblies that focus the light from a target on individual optical fibers, which are combined together in a final single optical fiber. The rest of the light is simultaneously collected in image devices, which record the field of view of each optical assembly. The gathered images are summed together to achieve a high-quality final image. These telescopes are not of interest only in the field of astronomy but also in the tracking of satellites and space junk. Industrial partners from the Astronomy, Astrophysics and telecommunications sector are being sought to collaborate through a patent licence agreement.

The device consists of a set of cameras located in the environment of each point of interest, an infrared lighting system, an image processing module and a wireless communication system with the train. The system contributes to the increase of safety in rail transport, providing the machinists with visual information about the state of the conflicting points and notifying the presence of obstacles. The system is capable of detecting the presence of objects in daylight and nighttime conditions. The group seeks for licensing agreements, technical cooperation agreements or commercial agreements with technical assistance, with companies that work in the manufacture of safety equipment for rail transport systems.
