AbstractThe concept of imaging might change in a way similar to the evolution of voice communication by telephone. It can be noted that many mobile telephones are today supplied with solid-state imaging, although at low resolution and at a low bit rate for data transfer. Therefore, in principle, there exist already wide-area mobile optical sensor arrays.LOIS provides excellent infrastructure, fast data transfer, massive computing, for the realization of a new generation of wide-area time-coherent imaging technology. The expansion of LOIS with optical sensor arrays is motivated both by technological/commercial reasons and by scientific reasons. The strategies, data base technology, and overall system technology for managing several hundred of time-coherent imaging units needs to be developed and tested in a full-scale system. The number of stations in ALIS (Auroral Large Imaging System) was an order of magnitude less but still required sophisticated techniques for control and management. The strong Nordic industrial background in telecommunications is of great value for the next step.
The atmosphere and ionosphere at midlatitudes can be explored either
passively or in combination by active radar experiments. Småland is a region
north of the densely populated areas in northern Europe providing reasonably
dark night skies for low light level imaging. The midlatitude atmospheric
signatures of the dynamic auroral oval as well as sporadic auroral events
are examples of ionospheric studies from Småland. Cloud physics studies and
environmental meteorological issues can also be studied using the wide-area
and the tomographic imaging capabilities.
