Results of a fast pnCCD detector system

摘要

Fully depleted, backside illuminated pnCCDs with an integrated frame store area and an anti-reflective-coating for the optical and near infrared region have been fabricated. Measurement results of a 51 μm pixelsize device with an imaging area of 264 x 264 pixel will be presented. The devices, which feature a doublesided readout, allow to be operated at frame rates higher than 1000 frames per second. The electronic noise contribution of the entire detector system is slightly above two electrons at fastest readout modes. We will also present the concept of a data acquisition system being able to handle pixel rates of more than 70 megapixel per second. Decentral data reduction and analysis units allow for a centroid determination of sub-images with a very low latency time. The high speed, low noise and high quantum efficiency makes this camera system an ideal instrument for wavefront sensors in adaptive optics systems.
