CMOS image sensors are capable of very high-speed non destructive readout, enabling many novel applications. To explore such applications, we designed and prototyped an experimental high speed imaging system based on a CMOS digital pixel sensor (DPS). The experimental system comprises a PCB that has the DPS chip interfaced to a PC via three I/O cards supported by an easy to use software environ...

All first-generation large-scale gravitational wave detectors are operated at the dark fringe and use a heterodyne readout employing radio frequency (RF) modulation-demodulation techniques. However, the experience in the currently running interferometers reveals several problems connected with a heterodyne readout, of which phase noise of the RF modulation is the most serious one. A homodyne de...

The readout chip for the CMS pixel detector has to deal with an enormous data rate. On-chip zero suppression is inevitable and hit data must be buffered locally during the latency of the first level trigger. Dead-time must be kept at a minimum. It is dominated by contributions coming from the readout. To keep it low an analog readout scheme has been adopted where pixel addresses are analog code...

Grain is a data analysis framework developed to be used with the novel Total Data Readout data acquisition system. In Total Data Readout all the electronics channels are read out asynchronously in singles mode and each data item is timestamped. Event building and analysis has to be done entirely in the software post-processing the data stream. A flexible and efficient event parser and the accom...

MAMMOS (Magnetic AMplifying Magneto-Optical System) is one of the highest density readout methods for storage media. The signal is directly amplified on the medium and its amplitude is just the same as that from a long domain. Even at a 0.04 Ilm domain, the signal was large enough. At a 0.2 Ilm packed domain, CNR was more than 50 dB and BER was in the 10-4 range. By employing a MAMMOS readout w...

The activities within the FERMI Collaboration were completed by the successful assembly of multi-chip module demonstrators fulfilling the technical requirements of the LHC generation of high performance detectors like CMS ECAL. Throughout the project, the Collaboration has been concentrating on providing architectures that fulfil the requirements set by the interested experiments in the domain ...

For an improved detection of cosmic ray muons with a threshold of 2.4 GeV, the KASCADE Central Detector has been upgraded with a new detector component built of limited streamer tubes. Combined with the operation of two layers of multiwire proportional chambers they enable studies of the muonic component of extensive air showers at higher particle densities. Due to the pad readout system of the...

We present a novel strategy for thrombin detection by combining a magnetic bead based agglutination assay and low-cost microfluidic disc. The detection method is based on an optomagnetic readout system implemented using a Blu-ray optical pickup unit (OPU) as main optoelectronic component. The assay, from sample to answer, is fully integrated on a microfluidic disc which embeds on-disc mixing en...
