Recently the effects of reduced bit-depth acquisition on swept-source optical coherence tomography (SS-OCT) image quality have been evaluated by using simulations and empirical studies, showing that image acquisition at 8-bit depth allows high system sensitivity with only a minimal drop in the signal-to-noise ratio compared to higher bit-depth systems. However, in these studies the 8-bit data i...

This paper prescnts tlic cxpericnce of using the Common Object Requcst Broker Architecture (CORBA)[ I] in tlic ATLAS prototype DAQ project[2]. Many coiiiniunication links in the DAQ systcm have been dcsigned and implcmentcd using thc CORBA standard. A public domain package, callcd Inter-Language Unification (ILU)[3] has bccn used to implement C O R M based communications between DAQ componcnts ...

The development of a novel and inexpensive sensor network for detecting the electrostatic field (ESF) of a charged bullet was explored in this paper. The principle method used to measure the ESF of the passing object was based on a voltage-controlled variable capacitance. This method utilized a varactor pair and sinusoidal input signal to produce a significant change in voltage proportional to ...

The Compact Muon Solenoid (CMS) detector at the CERN Large Hadron Collider (LHC) is undergoing an extensive Phase-II upgrade program to cope with challenging conditions of High-Luminosity LHC (HL-LHC). A new timing designed measure minimum ionizing particles (MIPs) a time resolution 30–60 ps during entire HL-LHC phase. common data acquisition (DAQ) system will collect from readout chips, recons...

This research is a continuation to our work which was published in [1]. Eight different timing VIs are designed and tested. These include ON-Delay, OFF-Delay, Single Shot, Retriggerable Monostable, and Accumulative software-based timers. Using hardware programmable counter/timer chip (DAQ-STC-24bit) and PCI MIO-16E-1 DAQ board, another two precise timers are designed. At the end of the paper, f...

Three-dimensional ultrasound computer tomography is a new imaging method for early breast cancer diagnosis. It promises reproducible images of the female breast in a high quality. However, it requires a time-consuming image reconstruction, which is currently executed on one PC. Parallel processing in reconfigurable hardware could accelerate signal and image processing. This paper evaluates the ...

The KamLAND-Zen experiment is searching for neutrinoless double-beta decay of 136 Xe. We are preparing the upgrade KamLAND detector, KamLAND2. It designed to improve discrimination power two-neutrino and cosmic-ray muon spallation backgrounds. Data acquisition all neutrino events from nearby supernova also an important issue KamLAND2 data rate a key factor design new DAQ system. High speed samp...

LabVIEW is a graphical programming language. LabVIEW provides the flexibility of integration of data acquisition software/hardware with the process control application software for automated test and measurement applications. In this paper, an effort is made to obtain a lissjous pattern using DAQ card and measure the phase difference between two signals acquire by DAQ. Also we try to replace th...
