Femtosecond coincidence imaging of multichannel multiphoton dynamics.
The novel technique of femtosecond time-resolved photoelectron-photoion coincidence imaging is applied to unravel dissociative ionization processes in a polyatomic molecule. Femtosecond coincidence imaging of CF3I photodynamics illustrates how competing multiphoton dissociation pathways can be distinguished, which would be impossible using photoelectron or ion imaging alone. Ion-electron energy...
متن کاملMultichannel Micro Elisa System
ELISA system was integrated into a glass microchip. Antigen-antibody and enzyme reactions were performed on a surface of microbeads which were packed in the chip. By monitoring the enzyme reaction product with a thermal lens microscope, good calibration curve was obtained with short assay time. Moreover, to realize higher throughput assay, a semi-automatic ELISA system with a 32-ch microchip wa...
متن کاملMultichannel ECG measurement system
Multichannel ECG is an important instrumentation for experimental and clinical electrophysiology. Both the software and the front-end design issues are described for a 128 channel system which can record the signals up to 100 seconds. The basic analysis and presentation of the acquired ECG signals are also given with examples of body surface potential maps. Thanks to the frequency response of t...
متن کاملVirtual Acoustic System with a Multichannel Headphone
The performance of current virtual acoustic systems is highly sensitive to the geometry of individual ear at high frequencies. The objective of this paper is to study a virtual acoustic system which may not be sensitive to individual ear shape. The incident sound field around ear is reproduced by using a multi-channel headphone. The results of computer simulations show that the desired sound pr...
متن کامل(1) a Fast Multichannel Analog Storage System*
A Multichannel Analog Storage System based on a commercial 32-channel parallel in/serial out (PISO) analog shift register is described. The basic unit is a single width CAMAC module containing 512 analog cells and the associated logic for data storage and subsequent readout. At sampling rates of up to 30 MHz the signals are strobed directly into the PISO. At higher rates signals are strobed int...
