我们在这里描述了嵌入OrthoPix架构的第一个单片像素检测器原型，专门设计用于处理每帧像素命中（占用）的相关数量很小（大约或小于1%）的成像应用，如高能物理，医学成像和其他应用。现有技术在像素单元中采用复杂的电路来区分相关信号，从而以大功率消耗和像素面积限制为代价实现极其有效的非破坏性压缩。OrthoPix架构实现了被动投影压缩方案，从而实现了低功耗、小像素单元和大面积器件。
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.
