Camera obscura — the Cherenkov imaging camera for EAS experiments

The operation of an imaging camera network is analysed at super high EAS energies (Eo > 1 PeV). The camera of the network is a pinhole camera (camera obscura) with several apertures and a PMT mosaic. The advantages of the camera obscura over mirror imaging telescopes are: low noise, wide field of view, absence of aberrations and simplicity of construction. The ability of the imaging camera to select EAS events helps in the design of a relatively simple data acquisition system for the network consisting of many cameras.
