A flexible and scalable, fully software-based lock-in amplifier for nonlinear spectroscopy
نویسندگان
چکیده
We demonstrate a cost-effective, fully software-based lock-in amplifier (LIA) implemented on commercial computer. The device is designed for application in nonlinear spectroscopy, such as transient absorption and coherent multidi-mensional but may be also used any other application. performance of our compared to state-of-the-art LIA with nearly identical results both devices. Advantages over hardwired electronic amplifiers the improved flexibility data analysis possibility arbitrary up-scaling number channels.

this study intends to investigate samuel beckett’s waiting for godot and endgame under the lacanian psychoanalysis. it begins by explaining the most important concepts of lacanian psychoanalysis. the beckettian characters are studied regarding their state of unconscious, and not the state of consciousness as is common in most beckett studies. according to lacan, language plays the sole role in ...
Lock - In Amplifier based on Virtual Instrumentation
When a slowly varying voltage is detected the main problem is the noise especially when it is several times greater than the signal itself. A lock-in amplifier is used to measure the small signals in presence of noise. The aim of this paper is to do a digital lock-in amplifier based on virtual instrument language LabVIEW and later on, it will replace a practice of a subject from the Physics’ de...
متن کاملUsing a Lock-In Amplifier
In this lab, we explore the principles of the use of a lock-in amplifier, using a He-Ne laser, light chopper, and a photodiode as the lock-in input. We explain and use the concepts of phase sensitive detection, dynamic reserve, and time constants to determine both the range of linearity of the photodiode in use, as well as the frequency response of the photodiode. Furthermore, we determine whet...
متن کاملRH Lock: A Scalable Hierarchical Spin Lock
Scalable architectures with non-uniform memory access time (NUMAs) have gained increased popularity in recent years. The increased scalability have increased the demand for scalable lock implementations, such as the queue-based locks of Mellor-Crummey and Scott (MCS lock), and of Craig, Landin and Hagersten (CLH lock). This paper demonstrates that the first-come first-served nature of queue-bas...
متن کاملA A Scalable Lock Manager for Multicores
Modern implementations of DBMS software are intended to take advantage of high core counts that are becoming common in high-end servers. However, we have observed that several database platforms, including MySQL, Shore-MT, and a commercial system, exhibit throughput collapse as load increases into over-saturation (where there are more request threads than cores), even for a workload with little...
