Abstract
We describe here the first monolithic pixel detector prototype embedding the OrthoPix architecture, specifically designed to deal with imaging applications where the relevant number of pixel hit per frame (occupancy) is small (on the order or less than 1%), like in High Energy Physics, Medical Imaging and other applications. Current state of the art employs complex circuitry into the pixel cell to discriminate relevant signals, leading to an extremely effective, non-destructive compression at the price of large power consumption and pixel area limitations. The OrthoPix architecture instead implements a passive projective compression scheme, leading to low power, small pixel cell and large area devices.
